Jabber, Inc., one of the companies that support the Jabber Software Foundation and all things Jabber in general, of course has a Chief Architect in the person of hildjj. He keeps tracks of the Musings from the Jabber, Inc. Architecture Group, which I immediately added as a channel in Mimir.
He's also written JEP-0080: Geographic Location Information, a data format for encoding geograhic information and transport it over Jabber. I am thinking of using this for the Jabber World Map over pubsub. And if that wasn't enough, he produced an internet draft with the IETF on TINS, a Transport for Initiating and Negotiating Sessions using SDPng over XMPP.
Keep up the good work!
