So what is the sense of having BDCs? I guess the biggest load happens 
when the profiles are copied; when there are hundreds of users, one PDC 
(on which the profiles are stored) would be much overloaded.

Besides, Samba Guide chapter 7 ("Distributed 2000 users network") 
describes a setup when users are located in New York, London etc. 
different locations, which sounds just silly if roaming profiles were 
stored for example in New York only.

I don't think giving the same NetBIOS name for different machines is a 
good idea.

Fetching profiles each time from a central server when user logs in / 
logs out doesn't seem to be good idea for me - what if company/school 
etc. has two or more buildings, and they are connected only by a slow 
VPN over internet/wireless etc.?
