В общем есть такое письмо:

It looks interesting, and certainly there are scenarios where this seems like a better solution than Linq2Sql or Entity Framework.
It also has some impressive performance numbers: http://ormbattle.net/

What counts against it is that it the documentation is scarce, and it doesn’t seem to have much of a user community.
Is this is one-man show? It’s hard to figure out who is involved. I see people on the forum complain about lack of support or answers to simple questions.

I would be skeptical about being dependent on something that could quickly become obsolete, even though the source code is available.
Unlike IoC/StructureMap it’s very hard to wrap DB code in such a way that we could easily switch providers later.

Just my opinion, I guess Jan and Peter would ultimately have to decide on this.
