I think what other people were not communicating correctly is that it 
*is* possible to put voip-url in presence, but it is *not* the 
desirable solution because not all clients want that information.

Of all the packets sent by Jabber, the <presence> packets are repeated 
and resent the most--so including extra information in everyone's 
<presence> packet greatly increases the network bandwidth 
demands--which would be ok except for the fact that very few people 
want the voip information, so it's a waste.

This is why things like having the currently-playing song in the 
<presence> are not a good idea--you end up resending presence every 
time a song changes, which adds up to a lot of wasted bandwidth, 
especially for mobile users who don't care that the song you're 
listening to changed.
