The German Linux Magazine runs a sponsored an "Open Source Lounge" at CeBIT each year. Last year I put in a proposal for DAViCal and it got accepted! With some airfare support from InternetNZ I got to showcase my Free Software project at the largest IT trade fair in the world.
If you have an open source project to promote I can't recommend this highly enough. Below is a review of my experience at CeBIT early this year. This is long overdue for posting, and I'm prompted now because submissions are now open for the Open Source Project Lounge at CeBIT in 2012. Apply now.
I've been very quiet on here for a few months, and the reason is (of course) because I've been doing other things. No surprise there, I guess!
What I've been doing, first of all, is writing aCal, an Android CalDAV client with a lot of help from Chris Noldus. It's probably fair to say that Chris did most of the heavy lifting while I learned Java, did most of the UI & graphic design, and the low-level CalDAV synchronisation and geeky calendaring code. This is now available in the Android market for NZD$2.00 to help us fund further development and in a few days (or a couple of weeks) I'll get the source code up somewhere public (probably Gitorious) and it will be licensed GPLv3... When I get a moment - although refer to title :-)
