I like Tapioca's distributed approach - nice use of DBus IMHO. 
:)

I'm really curious though, why you would use GStreamer for VoIP - 
you say on your website that:

"Many of the existent open source VoIP has a media subsystem of 
its own, which means that transport protocols and codec 
implementation are inside the application's code. That' s why I 
believe that a great feature in Tapioca is that it uses gstreamer 
to provide audio codecs, device handling and RTP streaming. This 
gives a lot of extensibility to the multimedia layer."

I'm not sure that makes sense to me since on the n770 the DSPs 
are sinks themselves - at least if this page:

http://maemo.org/pipermail/maemo-developers/2005-September/001217.html

is correct.  No other open source telephony apps use GStreamer 
(that I know of) and it looks like you'd have to hack it to make 
it work on an n770 and a desktop from the same code base... 
assuming you had software plugins for the codecs for GStreamer 
(do those exist?).

I do like getting the RTP framework of GStreamer, but for VoIP 
that seems like a heavy-weight option just for RTP.

Thoughts?
