Terminal Services on Windows 2008 has an option called RemoteApp which basically runs a full TS session but only brings the application window back (without the standard TS borders). To a user it looks like the app is local, but it isn't.
I believe Citrix supports this as well, in a technology called Seemless Window.
Are there any other remote desktop software that does this too? Something like VNC + Addon is also fine.

accordingly, UltraVNC supports seamless windows. XPRA also offers this functionality, but it's only for X sessions.
