How to label running an application over a WAN vs running an application on a TS

We have a Server/Client software that connects using ODBC. On a LAN the client is installed on each computer like a standard program.
We do support our programme when the Client is installed on a Terminal Server and the customers access the TS via RDC or Citrix and run our program on the TS.
We do not support our customers installing our programme Client on their remote computers and accessing the Server over the Internet (mainly due to the poor Internet infrastructure speeds in AUS).

We often get customers calling about both situations and referring to them both as WAN.

Is there a technical name definition between the two types?
If not does anyone have anything better than:
- WAN via App Server (or via Terminal Server)   -supported
- WAN via Local Computer   -not supported

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I would just take the word WAN out and use "Local Install" vs. "Terminal Server/RDC/Citrix Server Install"
