Kyte today have officially announced the full availability of their Mobile Producer application, a C++ based S60 application to help produce and distribute live streaming and pre-recorded mobile video and pictures. It sits alongside their Kyte Mobile java application which allows people to view media on the Kyte.tv service. It's a free download, just point your phone's browser to http://m.kyte.tv/get and choose the Mobile Producer.
I'll be taking a closer look at Kyte's mobile producer application in the next few days, but for now there's no reason for you not to load it up and have a little play. You will need to register with Kyte.tv but you have the option to do this from the handset, so there's little need to power up your desk bound web browser.
