Re: Our lead over SolNet...?

I have a few naive questions. Are both (all) groups starting from the
smallest keys and working up? (So the slower group's work is always
a) Why don't the groups work cooperatively, checking non-overlapping keys
sets first?
b) If cooperation isn't possible, why doesn't one group select keys by an
alternative method, ie. either at random, or starting from the other end?

(I gather from their web page that one group, the DES Violation group has
given up in response to SolNet progress.)
