I haven't been able to confirm, or even find mention of the RSA-576 being solved, by anyone as of yet.
And the way things keep changing over at Neo, I wouldn't put much weight into anything posted on their site.
As far as Free-DC's "official" posistion on the Neo issue, the concensus among the founders is basically "we don't care", with the notable exception. So whatever the team members decide, is how Free-DC will (not) respond.
