Perhaps I'm making a simple task seem too difficult. Could I get any best ideas on a method to do the following?

-Multiple servers, each connected to central server via VPN. No NT domain trusts.
-Each server has similar database (different db name) with identical tables within the db however.
-Each server needs to have a method of transferring some (not all) of the tables up to the central server.
-Each server is remote, and minimal administrative overhead is a necessity.

Currently, I'm trying to create a dts package for each of the servers (LOTS of them, so this is getting complicated) and having the tables update the central server. Is there a better way?
