Regarding email, the current idea is that the NSs for URS locking provided by the URS provider, reply with MX 0 . when queried for the MX of a URS locked domain name.
That would help, but since MX 0 . is not formally standardized* there's some other stuff that would help more. If I may ask a meta-question, who's writing on this spec, and who's providing technical and security advice?
