Hi Oliver, sorry for not replying sooner, we are in the middle of a development cycle so things are a little hectic.

We'd love to have your help creating a TurnKey Foswiki appliance. I think the fastest way to get the appliance off the ground would be to use TKLpatch, a simple appliance customization mechanism. You should also take a look at the community development notes.

Looking foward to collaborating with you and the Foswiki folks!
