I can't find anything on the topic, not even "Not possible"-threads, so asking is my last option before I decide whether it's worth the time to write a simple solution myself...

I'm looking for any webOS 1.4 XMPP client that is able to handle MUC (Multi User Chat). I run an XMPP server for my family and would like to set up conferences, but some of us are on WebOS where there seems to be a real dearth of suitable clients. Any pointers?
