If we ignore Cryptohaze-Multiforcer (which is totally obsolete) and focus on New-Multiforcer (the SVN builds):
Yes, it supports salted hashes across the network natively. There has been a good bit of work behind the scenes to make this happen - EVERY hash format supported in New-Multiforcer works across the network. Period. Even the complex stuff like the IKE PSK hashes work across the network. It's baked in.

MS-Cache V2 (also MSCASH2) are the domain credentials, stored locally. They're PBKDF2 with a fairly high round count.
NTLMv2 is a network exchange protocol used to authenticate to a remote server. They're quite different.
Both are on the support list. MSCACHE1 is done, and I'm taking a break from nasty kernels to add some more forum types, but MSCACHE2 is on the "within a week or two" list. NTLMv2 requires DES support, which I have for LM, so that won't be too bad either - just a few more pieces to put together.
