Something to ponder in terms of IM at future Summits. Could we not get everyone a "@maemo.org" or similar email address, hosted by Google. That way everyone is accessible via GTalk. In fact, that may just be useful in day to day dealings. You then just need to know that person's maemo.org username, ask for permission to IM them, and go from there.

In terms of the 5 minute talks - some went very well because the presenter obviously tailored their talk and demo for the 5 minutes. Many of the Fremantle Stars presentations, or Jaffa's Development Nirvana presentation are fine examples of this. Unfortunately, technical glitches can occur, such as what happened to lcuk in his liqbase presentation. In that particular case, I was surprised that the there wasn't a larger effort to get his TV out working (if that was the problem).
