Gringo: a more effective strategy (assuming there's no TM, as your friend is not the TM holder, just a dealer apparently) would be to do a Google search for all links to the old domain, and then get those websites to change the links.
If your friend has the old webserver logs for the original site, even better would be to look through it for the top referring sites, and get those ones to change the links. The domain without the hyphen is better, anyhow, for the long run.
From their WHOIS info (and that for "provenhealthy.com", which they link to on their current page), the data seems fake. See:

Area code 702 is in Nevada. That address doesn't seem to be in Nevada. Complain to eNom (directly, and also via the form at
www.internic.net that I mentioned above), and perhaps you can have the last laugh, by not only having your friend's domain deleted, but also their provenhealthy.com one.
As an aside, perhaps GregR might want to create free sub-categories for any registrar that wants to be represented on DNForum.com, for semi-official support? e.g. if eNom, OpenSRS, Register.com, DirectNic, Dotster, etc. have people watching the board already, they can have an area where their reps would be able to provide some info? Of course, it all depends on the registrar if they want to provide such support (might be a useful marketing thing to them, esp. with so many domain owners here).
