Great idea. Probably it'll help a lot, because I don't know why, but
RequestAlias takes a long time to return. Seems to be the most expensive of
all when we're testing an IM client. (We've tested it on colligo, but
probably is because it blocks the ui)
On a similar note, I was considering an API on the Connection, something

This is awsome!!
I love that, but is there no problem to pass a big bunch of data through
dbus? I mean, handle uri + presence + alias + avatar (data) + extra infos
Well anyhow I don't think it'll be so big ...
