Comment:

 Up until recently there was not any viable, useful invisibility support
 for XMPP at a protocol level, this has only just recently become
 reasonable to support. It has not yet happened because no one with the
 time, interest, and knowledge has written it.

 The invisibility support that pidgin will accept (and which I hope to
 eventually have time to implement) will be that specified by
 [http://www.xmpp.org/extensions/xep-0186.html XEP-0186] (unless that is
 retracted or superseded by the time I get to it). You are free to try the
 snippets provided by that XEP in the XMPP Console, but realize that your
 server may not support it. Furthermore, pidgin will still automatically
 respond to certain requests even once you have sent the invisible command
 and that will betray your online presence.

 Alternatively, it is possible to send a presence stanza of type
 unavailable to the server which *may* convey some/many of the invisibility
 'benefits' but also may do things you don't want.

 Neither of those methods allow for being invisible only to specific
 buddies however.
