[jdev] Question on Presence, Invisibility and MUC

In my XMPP application, users can exchange both private messages and
presence and join MUCs. Ok, simple enough. I've implemented invisibility
according to XEP-0126. I'd like the users to be still able to join MUCs
while invisible, though. The issue I'm running into is that the first step
in going invisible is sending an unavailable presence for broadcasting to
all contacts: <presence type='unavailable'/>
Unfortunately for me, this has the additional effect of kicking the user
out of any MUCs they'd joined in that particular session. I've already
figured out how to tweak the privacy list so users can join MUCs while
invisible to individual contacts, basically it just looks like
<item action='deny' order='2'>
But I'm running into this problem when the user tries to go "globally"
invisible while already in one or more MUCs. Is there any way around this?
My initial thought was to direct the unavailable presence to only the
primary (IM) domain rather than having no "to" as indicated in the XEP, but
that doesn't seem to broadcast to anybody, so contacts who already thought
the user was online will continue to think so.
Is there any way around this? Or will I have to change my approach to
