I checked and the Pro version is not redistributable, but of course the
GPL version is.  We'll probably just package the GPL version for
distribution in the Ubuntu repository (and hopefully to the main Debian
repository too).  For the Pro version, we'll either just post the .deb
on our site or do an installer.

x86, x86_64, and possibly SPARC, IIRC.

Hmm... ok.  Will the GPL version be eligible for universe?  Are universe
packages reviewed more quickly?
