Don't believe it is. I got them when the camp-fire campaign (something like Kickstarter) was running; the same link that broadsword80 shared. The campaign was running for a month late last year.
Well, I decided to bite the bullet and support the project.
If you're overseas, Campfire themselves actually recommend using Tenso for overseas shipping.
Aside from the obvious requirement that is listed out on the MD@Home page, I'd like to know about the following:
Is hosting a node while the server is connected to a VPN allowed (though VPN is connected to the same country)
Required OS that the client runs on. I'm guessing it's Windows or Linux?
