This is one way that using a library will be not so useful. Since afaik most 
messageing serverices only use once connection per client.  Kopete is the 
best solution for this since it already runs as a process and has a DCOP 
interface started.

Yes, jabber has quite a few short commings over commercial messageing support.  
While it is very flexable, I have had nothing but problems interfaceing with 
my freinds and relitives on other services.  The jabber servers work just 
fine though.  Again this is why Kopete is a better solution.  It supports 
many protocols and is very flexable.

Yes, but how many messageing servers are truly P2P, afaik there is that KChat, 
but I have not clue how it works and no clue if its supported by anyone.

Really though if you are looking for an extensable messageing library what you 
really want is Kopte, we can have plugins that will support anything.  I even 
have seen a plugin for winpopups in the works.  Like it or not we are the 
minority here, so if we wish to message with others we should pick the most 
compatable solution.  So my advice is for the psi developer to get into 
contact with kopete and see if they need help.

Just my 2c...
