OpenBSD already supports bcrypt, but only supports bcrypt (in base, anyway; you could of course provide a bsd-auth authentication type to handle something else, the interface is reasonably simple to work with). Another possibility would be to teach the other OS about bcrypt, maybe this helps http://serverfault.com/questions/10585/enable-blowfish-based-hash-support-for-crypt/11685#11685
