I'm guessing a little bit here but not too much. 
When you say "not too much", do you have other information, or are you just pretty confident in your guess?
If they're the same people, they were smart enough at least to host p2ptechforsale.com on a completely different server with a private domain registration.
The reason I ask is because I've seen a few sites being sold lately. It looks like there might even be a turnkey p2p lending script out there.
Here's one site -
http://marketplace.sitepoint.com/auctions/21008. Just noticed the text on your link has a reference to Sitepoint in it.
Well, that's the only one I can find for sale right now. Found it advertised two different places, so maybe I was thinking there were more than just the one.
