If your interested in how the Windows Home Server Console does its thing using RDP
this site should offer a good starting point. If you just want to lunch a specific program using RDP with the full desktop, in the remote desktop connection client click on Options then click on Programs and check "Start the following program on connection". Then specify the program and the path to that program on the remote desktop along with any argument to pass into it when it starts. When you connect only that program will appear in the RDP session, in fact this is essentially how WHS console sets up it's own RDP session passing in the location of the HomeServerConsole.exe on the server along with the -b argument to remove its window chrome. Of course, there is some other work done with WHS connector on the client side to allow things to execute locally on the client such help files in the help viewer and URLs in the browser on the client but you get the idea.
With this said however, as Ken mentioned this will only work if the remote computer is able to receive desktop connections. Going further, it sounds like this violates the WHS Development guidelines for add-ins as well, specifically "The console is not a general-purpose desktop" part of the guidelines. The reason that the development guidelines strongly suggest against this is that the WHS console is really just meant for one person to use, the WHS Administrator. As such there are a few caveats that go along with is such as when a new instance of the console is opened any other console instances are instantly terminated. This obviously would not be a good thing if you plan on having multiple people configure the workstations simultaneously. Following the WHS development guidelines you would probably want to build some type of service that is then hosted on the server using the WHS Console to configure the service running on the server. Then you would have your client application on the workstations retrieve their configurations from the server either though a polling mechanism or as Ken mentioned a push mechanism.
Hope this helps.
