I've been hacking on a project to help people find out who among their
friends has a couch the can crash on, www.stayover.at. Think couch
surfing for your social graph. It would be cool to be able to have a
view which was, listing which conferences you're attending, and then
you could either offer or find a place to stay with fellow attendees.

The problem is there's not api for it. And although i could scrape it,
for big conferences i'd have to paginate through the list of attendees
like this: http://lanyrd.com/2011/leweb/attendees/

Ideally there'd be a way to get a list of conferences simple by your
twitter handle. Then look up attendees by conference. I think for my
case, it could be done without needing to do an OAuth dance. It's just
reading public info, no posting back.

Oh, and one other thing, please provide a JSON format. It makes it
much easier to pass in to data structures than the xml mess.
