Hi Quentin,

I'm looking at exactly the same scenario (several geographically 
separated buildings with T1 connectivity), with the added bonus of far 
too common network outages.

My plan is to have each of the site servers configured, effectively, as 
BDCs, each with their own LDAP server (slaved from the primary at the 
DO) and Samba authenticating local clients. The only difference between 
this and your stated goals is that not even authentication would 
traverse the WAN, just internet and the occasional user's data if 
they're away from their home site. I entertained the idea of using rsync 
to keep up to date files from all sites on all servers, but the times it 
would be needed are so few and far between that I didn't deem it 
worthwhile. I will be rsyncing all machines to one central server 
nightly for backups, which would also make a fine place to migrate a 
user from one site to another.

Hope this helps,
