We're actively seeking suggestions for this year's event. The Session page has the currently-scheduled topics, but we'd like to hear more ideas.
On the short list so far is a session on printer setup for non-natively-supported devices.
Also note that registration fees are waived for presenters (though we do encourage a contribution in a similar amount).
Cheers
