I just picked this up off Appletell. It seems that there is a work around that now allows you to download a plugin. Once installed (which is easy) the plugin loads up MeBeam in your browser and starts a flash video chat. When you want to videochat with someone, ctrl-click (or right-click) them and choose “Initiate MeBeam Videochat”. That’s all! If anyone adds this let me know and we can try it out!
