I have qik account, wanted to state it has an android app as well. Some set up 2 accounts, so one publishes right away to facebook, twitter, youtube etc., and another, that you can select to publish w later. I know several users that use them on the go and to get published quickly to other social networks and youtube. I have had some sync'ing problems with voice and video could be the 2nd hand android phone though. You can also upload after, for storage or to publish later after you have viewed it.
there is also bambuster live streaming video app as well you may want to try out, I have both on my phone, but have only tried the qik.
