You probably want to ask these questions on the JDEV list, which is for 
developers (this list is for end users):

Sure, we've been building IM+presence systems with XMPP since 1999.

We think so.

SIMPLE is for IM and presence. You don't need Jingle for that, just 
basic XMPP as defined in RFCs 3920 and 3921. Jingle is a set of XMPP 
extensions that gives you the ability to negotiate things like voice and 
video sessions on top of XMPP.

The XMPP Standards Foundation (formerly the Jabber Software Foundation) 
manages the protocol standards. There are many open-source projects that 
you can contribute to for both servers and clients, go here for details:
