Comment (by johnmoody):

 Utilizes the same buddy selection style as the 'Add buddy pounce' dialog
 but with a new filter method
 'pidgin_screenname_autocomplete_online_only_filter' so the buddy selection
 only shows on-line buddies.  I haven't looked at removing buddies
 currently in the conference.

 This raises the question, do all protocols support a conference style
 function?  If so, should we allow cross-protocol conferences?  Do we have
 a flag within the protocol account that we can check for conference
 support and only show users currently logged onto a protocol that does
 support conferences?

 The new Invite dialog box now has three fields, the first defaulting to
 the protocol of the current conference.  I have greyed-out this account
 dropdown box but I haven't limited the buddies to just this protocol, in
 the Utopian hope that we can one day support cross-protocol conferences.

 The testing I have done shows you can select an MSN buddy, while in a
 Yahoo conference, but the attempt appears to be ignored.  Not sure if this
 is due to being a cross-protocol request (I don't think so) or more likely
 that MSN doesn't support the conference style chat.
