Where is the Mac OS X version, for a truly portable(TM) desktop side (as long as the LInux version compiles for BSD etc)

Paris, because she knows how things fit.

Except for the "perpetual" licence bit.

Seems a lot of money to part with considering Unison is a start-up. If they fold within a few years your "perpetual licence" won't seem so perpetual then.

It depends on the number of licenses. $36k is one year for 720 users, according with the article, so in between the 20-1000 employees they mention as SMB, or whatever. My university employs thousands, for example, so I guess it would be a better deal to pay $36k once.

Let's all have less stability than Windows! This is just a halfassed attempt by Canonical to become profitable. If this startup had any brains they'd ally themselves with Red Hat if they need a corporate sponsor.
