I have been recently watching at the development of TVP (The Venice Project), now joost.
I managed to get a beta invite early in the process and have now some invites for other beta testers.
Drop a line if you want one. nothing official yet.. Maybe it will come with the launch?
They are working on a linux release, but
Si quieres una invitación para joost, avisame y dejame tu e-mail.
Esperemos que ya venga una versión para linux.
