[RC5] Partial work saved during time limit shutdown?

Yes, you can configure multiple clients to use the same buff* files.
You cannot safely share checkpoint files, however - perhaps this is
the point that may have confused you.
Shared buffer files are a supported configuration, but not one we
recommend. There are limits to this approach, as only one dnetc can
access the buffer files at a time. There are also some rare
circumstances where one bad egg can damage a shared buffer file. (Not
sure of the details, ask bovine if you're curious)
If you have more than a handful of machines, you may want to consider
using a perproxy, and configuring each client to use a very small
local buffer (say, 2). The client is unable to save work-in-progress
to the perproxy, but with a source of work "nearby", the risks of
having a small buffer file are minimized.
