Perhaps larger than RC128? DEFINITELY! 

The keyservers and clients don't store a whole key, they store an OFFSET
that describes the keyblock. So they don't keep information about all of
the 268million keys in a block, just the offset for the beginning of the

Describing a board configuration and the move therein would take a lot more
data than describing a single RC-128 key, and describing all possible board
configurations and all possible moves for that board. Whoa, that's a HUGRE
