If each site has less than 1k users and are connected via a T1 I don't think you even need to have local DCs. Clients at the remote offices will still be able to log on and access resources if the network is available because of cached credentials. If your network is full fledged T1s then there shouldn't be any network outages long enough to run into the problem of cached credentials expiring.
What I would look at is the network load on the T1s, the estimated logon traffic generated by 1k users and compare that to the estimated replication traffic generated by AD. Often times in a fairly large AD environment you will find that the authentication traffic of 1k users will be smaller than the replication traffic of AD. If your T1 connections can support the authentication traffic of 1k users then I wouldn't bother putting a local DC at those locations. Just make sure you size your main office DCs to support the load of the remote offices.
