I don't believe the N800 supports USB networking in that sense, it only
supports wifi.  A BT Home Hub is a BT Broadband branded wifi hub,
probably a neighbours.

If your NTL cable modem doesn't have a wifi router built in, the easiest
thing to do would be to get one, they are very cheap these days.

I do 99% of my maemo development whilst online in a scratchbox, so it
works. :)

Scratchbox isn't an emulator really, nothing is emulated. But an
inserted MMC card on your machine will be accessible from the
scratchbox.

Yes.

The scratchbox /dev is the same as as the /dev outside of scratchbox, so
you can mount it to a patch inside scratchbox.  You'll need to install
mount (apt-get install mount), but apart from that it should just work.
If scratchbox gets in the way, just mount it outside of scratchbox to a
directory which is inside your scratchbox, such
as /scratchbox/users/[username]/targets/SDK_X86/media/mmc1

Heh, yeah, you were trying to run the shell.  Install osso-xterm from
maemo-hackers.org.
