Hunter;
How does it work with say; 50 or 100 users?
I think that remote desktop represents a great solution as long as you keep app restricted to few concurrent users. Furthermore, remote desktop does not add a web-clients such as a PHP client, Java client, web services, etc... Neither will it give you triggers, referential integrity rules, and extended field types.
Again, as long as you keep your app restricted to older technologies and a few number of concurrent users, your should be fine with a remote desktop.
