Ulmo apparently hangs out in Endorë most of the time and can do resurrections as well.
There has been debate about letting non-Valar people do resurrections but there is concern about potential for abuse (forking, uploading). The book mentions that recent improvements should obviate that problem and that Mandos has since started teaching more people.
