It does not naively seem like a lot of work to figure this out. Your jobs 
are either not started yet, started on a particular client, or finished and 
reported back to the master. The only time recovery of a client or master is 
difficult is the middle case, where part of the rendering is finished. In 
that case, when the client recovers, you get the data off the disk and start 
rendering again with a -C option, or you copy the partially-complete files 
to a new machine and fire up povray there with a -C.

What exactly do you think are the problems with failed clients? Do you have 
individual frames spread over multiple clients, or individual clients 
rendering multiple frames in parallel, or something like that?
