Here's the scenario.
We have a Windows 2003 Web Server (oursite.com) that serves our site (I know, sorry.) I use a Centos server to serve a lot of content into that main site (oursitelabs.com).
The oursite.com DNS is managed by Network Solutions (again, I know) and I manage the outsitelabs.com directly through MediaTemple.
I have setup a Wordpress MU installation on the Centos server (oursitelabs.com) in the domain root. I would like several blogs there oursitelabs.com/media-relations for example to be accessible at oursite.com/media-relations. We need for the visible uris to always be oursite.com/media-relations/whatever-the-post-is even though the area is physically hosted at oursitelabs.com.
Any advice on how to setup DNS/Windows/Centos/Wordpress to make this happen?
