I had a big argument with Sedo about this a few days ago. I proved to them that eNom HAS NOT changed their policy about pushing names... there is no 60 day lock.
Let me know if they insist on this, I'll email you my email thread with them, including statements from 2 eNom support people.
I will not wait 6 weeks for a buyer to figure out a transfer while a simple eNom push can be completed in 1 day. I had 4 name sales held up for weeks over this issue.
One exception... if the name has been at eNom less than 60 days, obviously the lock goes with the domain after the push.
