Yeah agreed that's not super nice, but it wouldn't be too hard to change this. I just wanted to avoid symlinks complexity - trashing foo- dirs can be done safely with the current scheme.

Eh well, looking at fabric in more details I guess it might be good after all. I will give it a shot. I discarded it as a capistrano-like solution but it seems much less magic and more explicit, which sounds great.
