Perhaps the ID numbers of some already checked key block could be used. In
of the future versions of the client maybe something like this could be
The ID of a key block would be hard coded into a client ex. 193239:30000000.
Now this block has already been checked and is known not to contain the key.
The information contained in this block would be a number representing the
percentage of the totally checked keyspace. Say 15%
Since the keys are distributed sequentially the client would know, when it
ran out of keys and went into the random generating routine, to only generate
keys for the remaining 85% of the keyspace.
I feel this would significantly reduce the number of duplicate key blocks
generated. Of course as the key space gets more and more exhausted more and
more duplicates would be generated.
Perhaps another piece of data that could be passed via another key id would
relatively large gaps in the checked key space (tardy blocks) which could be
added to the free key space generation.
Another idea is to use the key id to automatically stop and deinstall the
clients once the key is found.
