Internet video platform Joost is inching closer to a public launch. Last week the Joost announced partnerships with 32 advertisers. Today the company announced that it is allowing current users to send an unlimited number of Joost invitations to their friends.

This is sort of the Gmail version of a public beta. You can't just sign up through the Joost homepage yet, but it shouldn't be too hard to track down an invitation if you want one. Up until now, each user got a limited number of invites to distribute.

You'll need to download the latest version of Joost, which is 0.9.4. As of about noon, unlimited invites still don't seem to be available, but expect an update later today.
