The video-editing service Eyespot, a rival to Yahoo's Jumpcut, will announce the launch of a new mobile feature later today.
"MobileCast" isn't well-suited to written descriptions (the video below is much more informative), but it's basically a way to create your own mobile video channel and broadcast your videos to subscribers on their phones. The change isn't applicable to every video, however: MobileCasts work with the groups feature, meaning that it's really about beaming clips to those who are already interested in your content - if you're a videoblogger, for instance.
More new stuff being announced by Eyespot later includes a desktop uploader (Mac only for now, which is unusual), improved search and the Disturibia contest we mentioned previously. Somebody acquire these guys already.
