[JDEV] URL form of JID?

[Jens Alfke]

Is there a standard way to represent a JID as a URL (analogous to a 
mailto: URL)? The most basic form would be something like 
"jabber:user at host/resource" and the default action when clicked would be 
to send an IM to that user.

It occurs to me that a second form would be useful for conferences / 
chat-rooms, since the behavior of clicking the URL would be different 
(joining the room.) AIM, I believe, uses a "?" attribute on the "aim:" 
URL to distinguish between these things.
