[maemo-users] DUN via bluetooth - with Verizon?

I did a quick check of the Verizon Wireless www site to update myself on 
how they are marketing the service called "Broadband Access".  I have 
been using the service with a Verizon XV6700 tethered to the N800 via 
bluetooth. My experience is similar to Jeff's in that the N800 acts as 
an "I just want to be connected all the time" kind of device so that 
when I carry both the Verizon Mobile handset and my N800 together the 
N800 remains tethered and connected to the Internet via the BT DUN.

Having said that, it should also be pointed out that the service does 
have  caveats and limitations which are stated in the Terms and 
Conditions of offer contained on the www page whose url is:


Here is a summary of those limitations:


    Prohibited Uses. While most common uses for Internet are permitted
    by your Data Plan, there are certain uses that cause extreme network
    capacity issues and interference with the network. These are not
    uses intended by our Data Access plans and are therefore prohibited.
    Examples of prohibited uses include the following:

        (i) server devices or host computer applications, including, but
        not limited to, continuous Web camera posts or broadcasts,
        automatic data feeds, automated machine-to-machine connections
        or peer-to-peer (P2P) file-sharing;

        (ii) as a substitute or backup for private lines or dedicated
        data connections;

        (iii) "auto-responders," "cancel-bots," or similar automated or
        manual routines which generate excessive amounts of net traffic,
        or which disrupt net user groups or email use by others;

        (iv) "spam" or unsolicited commercial or bulk email (or
        activities that have the effect of facilitating unsolicited
        commercial email or unsolicited bulk email);

        (v) any activity that adversely affects the ability of other
        people or systems to use either Verizon Wireless Services or
        other parties' Internet-based resources, including "denial of
        service" (DoS) attacks against another network host or
        individual user;

        (vi) accessing, or attempting to access without authority, the
        accounts of others, or to penetrate, or attempt to penetrate,
        security measures of Verizon Wireless' or another entity's
        network or systems; or

        (vii) software or other devices that maintain continuous active
        Internet connections when a computer's connection would
        otherwise be idle or any "keep alive" functions, unless they
        adhere to Verizon Wireless' data retry requirements, which may
        be changed from time to time. This means, by way of example
        only, that using these Data Plans or Features for P2P
        file-sharing services, web broadcasting, or for the operation of
        servers, telemetry devices and/or Supervisory Control and Data
        Acquisition devices is prohibited.

    *If usage exceeds 5 GB per line during any billing period, we
    reserve the right to reduce throughput speeds of any application
    that would otherwise exceed such speed to a maximum of approximately
    200 Kbps*. These speeds are subject to change, in our reasonable
    discretion, in order to address network issues. In order to assess
    your usage, you may obtain information about your usage during a
    particular billing period, including during the Return Period under
    your Worry Free Guarantee, through My Account or by contacting
    Customer Service. These Data Plans or Features are for individual
    use only and not for resale. We further reserve the right to take
    measures to protect our network from harm, compromised capacity or
    degradation in performance, any of which may impact permitted data
    flows. Accordingly, we reserve the right to deny, modify or
    terminate service, without notice, to anyone we believe is using
    Data Plans or Features in any manner that adversely impacts our
    network or service levels, and we also reserve the right to
    terminate service upon expiration of the Customer Agreement term.

    We may, but are not required to, monitor your compliance, or the
    compliance of other subscribers, with the terms, conditions, or
    policies of the Customer Agreement.

    Verizon Wireless Plans, Rate and Coverage Areas, rates, agreement
    provisions, business practices, procedures and policies are subject
    to change as specified in the Customer Agreement.
