From posted results, no freeware engine is close to the strength of Ruffian. You mentioned yourself, that it is "easy" to reach some 2300 Elo level, but it is very hard, to improve Crafty. Why should anybody, that can improve any freeware engine that much, not be able, to write it from scratch anyway? If I look at the position Will posted, (not only) the search depth really is impressive. It seems to indicate, that Ruffian uses some clever pruning. >2.

AFAIK it is not available for Unix systems. Ruffian, when logged into ICC shows an interface line with xboard. Unix versions are expected soon. >5.
