[With apologies if this has been well-covered elsewhere, but I've just
spent half an hour scouring archives and couldn't find it.  Please
direct me to any discussion which might already have taken place on
this subject]

We're covering the keyspace in a nearly linear fashion.  That is, a
part of the whole keyspace is allocated to someone, then that part is
assumed to be processed.  The reality is, of course, that some parts
will be trashed by dying hard disks (he says, sheepishly), some will
be lost by "dead participants" (which discussion I have read).  Plus
there are blocks which get "stale" and don't come back for absolutely

My idea to fill the gaps is relatively straightforward:  Those of us
with permanent connections (as I have from one machine but not from
the others) could look to a proxy which maintains the keyblocks which
have, supposedly, already been allocated for processing.  Since these
machines are permanently on, the blocks would be returned within a
reasonable timeframe, say a day or two, without the usual "stale
block" problems, and we could probably achieve 100% coverage of at
least a handful of the key superblocks.
