That sounds like a great project, good luck with it!

I do not think that we currently have any simple way to record
liquidsoap's current state, so you may have to indeed keep track of
the state on your own in case of a crash.

This is, however, an interesting feature. I do not know how
feasible/easy it is, for instance all temporary files would have to be
downloaded again, but it is certainly worth thinking of..
