Bambuser (my archived videocasts) is another competitor to qix and flixwagon. It's out of Sweden.
Observations after a couple of 'casts:
Qik Alpha Version 0.26 appears to have solved the hanging problem when the WiFi access point is not available. Thanks Qik for the timely and very quick updates!
The current alpha (so fix it please ASAP :-) ) version of Qik hangs forever if the WiFi Access point you have configured is not available. Here's the steps to reproduce this:
Other than this bug, I am pretty happy with Qik. It's a great service.

The above photo shows my "bicyclecast" setup (Gorillapod + N95 + DT-22 Tripod Adapter + my bicycle). It worked for only 6 minutes of my 30 minute commute to work (bug? limited buffering capacity? EDGE too slow?). And was fun. The GorillaPod doesn't keep the camera too snug on the bike but it's low budget, cheap and cheerful. Someday I'll have the money to buy a proper bike tripod camera mount like the pros use for Tour de France videos!
