I like this idea, building dfas is something useful to do on opponent time.
Of course the practical difficulties might be great, as we don't have much
infrastructure for doing anything while waiting.

As to debugging, it should be pretty easy to store how far we have got at
each move, and rebuild the dfa accordingly.

This would make machine-machine games trickier, expecially if the opponent
is a really fast one. Also, regressions would have to start by building the
dfa's, at least once for each test set, if not for every test script -
horribly slow.

So, in real life I am not too sure if the small philosophical benefits would
be wort the costs...

Just my $0.02, anyway.
