Dwayne, are these based on RDP technology under the hood, or are they more like BeTwin with actual separate sessions? I.e. do you have a separate video card (or a separate head on a multi-head video card) for each session? And does each one really see a completely separate Windows session with separate login and all that?
Dwayne will obviously be the expert here, but based on what I have read from N-computing, each touchscreen (using a Ncomputing device) is its own seperate session on the remote PC, so it is not like RDP. The new N-computing device that Touchtronix is using, communicates to the host PC over a traditional IP network, through the standard NIC in the host PC; so no need for a multi-head video adapter.
This gives each screen the ability to have a completely unique session on the remote PC. Essentially, each screen is a fully functional PC session, with a touchscreen interface loaded on it...but there is no reason why you couldn't exit the interface, and open a web browser or other application.
The older N-computing devices used a propriatary network, that connected to the host PC through a special PCI card, but now it is all over IP.
One of the big draws for me to this system, is the fact that you only need to run one Cat5e/6 cable to each screen for network. The other thing I like is that the IP touch comes standard with the ability to use either a LV power over 18/2 from a central location, or a direct HV connection at the screen. So if you wanted to used LV, you would run one Cat5e/6 and one 18/2 to each screen, if you used HV, you would run one Cat5e/6; but you would need a HV commenction at the screen for this setup.
