May be I got a false info here, but as far as I understand, you need CIFS if you want to access certain Windows box, like 2003 server and XP on the 2003 domain. Cuz SMB base on the old LANMAN, and it won't work w/ the new 2003 domain. I'm not sure what you need the SMB for, but you may need CIFS as well. And yes, I'm looking forward to streaming video from my Windows box as well.
