I had a sandstorm instance for a while, but stopped using it due to the dwindling community. There are some alternatives now, but the best part about Sandstorm in particular was the small atomic backups for each Web app you had. I haven't seen other system try to abstract above the applications like that...
Sandstorm was really ahead of its time. This is a super hard thing to know, but if what you are doing resonates with too small of a population it will take a long time become popular.
I could have seen it be a great software dimension to home routers and NAS boxes.
