Multiple DTS servers

We are in need of using a centralized application server with multiple live servers in different buildings with different web servers. It would be a real help if we could have each server have its own DTS server. This way we do not have to rely on opening up more ports on the firewalls to allow the external webserver access to the main DTS webserver.

This also would eliminate the issue of having the other servers rely on one DTS server. If the
DTS server fails or is offline for updates than the other servers would not having access to the DTS, therefore these external server would not have the dynamic services running that require the DTS
