Using Terminal Services for a single APP

Archived from groups: microsoft.public.win2000.setup (More info?)

I am new to TS.

I have an organization with 7 locations. They each have their own domain,
which is how we want it for now.

The issue is - they have an application that handles scheduling and other
important functions. This app is installed at each site, and each site has
its own data. It would be very very useful if this app could share the same
data across all locations.

I thought VPN would be the solution. It is far too slow. My next thought
is Terminal Services. However, each location will want to keep their
existing desktop/domain network configuration AS IS.

So my question is - Is there a way that Terminal Services can share a
single app, not the desktop as a whole, across the Internet. Basically,
users could log in to their own domain as usual, and click on the app icon,
which will launch a TS window for the application.

Any ideas?
