I'm not saying that you need a local SQL Server at all.

What is it that you are replicating? SO data, Look Ups? Customer excuses?

IMO I would not allow the replication out of a secure back end data that is dynamic, but I would allow static info. Plainly put Look ups I consider static, rarely chaning. Sales Orders, Invoice Details are very much dynamic and they only belong on the system's server.

Granted you could configure a Large Wan system that maintained data between Europe, North America, South America and ???. Running that through a single WAN might get sluggish, but then airlines do this all the time and their systems are not that slow.

What are they doing differently? Optimizing for true C/S and not some hybrid that us VFP guys can gell together. Just pull what you need and only what you need. I left a large law system on SQL Server that ran 8 offices on 1 server. They were only 1500 miles apart but it was perky.

In that same company we also did a local SQL Server for Document Managment. It was overkill but that is what partnership wanted.

So I guess that we should try to see things in a different way every once in a while. If we do that we may be able to break our mold on how we accomplish our repetitive tasks.
