If you head on over to Qik you can set up an application on your phone if it's listed here. With this application you can record video and instantly stream it onto your account for all your friends to see. If you want to notify people you're about to stream, there's an option to send a text or email with a link to your site.
I've already taken the liberty of making a Coachella group so just join and let's rape the benefits of this site for all to see.
ps. Blackberry Storm Owners
If you want the application you have to go to crackberry.com on your phone and scroll down to the post about qik. Click the image and your download should start.
