If you’ve got a Mac and want in on the Live Mesh Tech Preview, this just got posted on the forum:

We’ve had an outstanding response to our Live Mesh software for Mac and we’ve hit the current limit for the tech preview.

We’ll be monitoring the system for any issues before we open up more invitations. Please keep an eye on the forum to find out when more invitations will be made available.

Thank you,

The Live Mesh Team
