That was an early borrowing from another effort, and predates the JEP 
process. I think we would do better now. How much better is another
question. :)

My feeling is that it would be nice to use xcal, but that effort seems
to be on hold. Perhaps the best thing would be to re-ignite xcal?

Also, this comes down to requirements. Are we doing a new calendaring
system on top of XMPP? What will these calendaring applications look
like -- standalone? built into existing Jabber clients? a little of
both? This is a new application area for the Jabber community, which
means we need to put some thought into how we proceed, I think. We might
even want to form a JIG devoted to it.
