any news on BDC and trust relationship progress?

[Andreas]

Are there any news regarding:

1. Samba (2.2 or 3.0alpha) working as a BDC? Or just the net rpc vampire
   command for now?
   Should net rpc vampire work with a win2k PDC or just NT4?

2. Samba (2.2 or 3.0alpha) with trust relationships with an NT4 PDC? Or
   win2k?

Thanks.
