I have very little free time these days so can't really make much progress on Rcomage.
The absolute latest will always be in the 'zinga' branch from GitHub, but you'll need to compile the code yourself.
'Stable' versions is largely arbitrary, and Rcomage is never really stable anyway =P

Don't worry about "abuse of hospitality" - ask whatever you want :)  I'm happy to provide info anyway.
Whether or not I implement changes is another matter though.
