Kenneth, <div>Before my retirement from NC State I have done extensive work on accessibility of remote application. If I understand you correctly you are planing to deploy Windows application using a image on a remote server and use RDP for access.</div>

I would treat a virtual computer lab the same way that you would a physical one. Some of our IT folks are playing around with the idea of virtual labs too. I think the key is to provide a variety of accessibility options.<br>
In many of our labs we provide screen readers, magnification, speech recognition and some kind of scan-and-read software. I would think if virtual labs are a part of a program then providing accessibility to them would be the institution's legal responsibility.<br>
The virtual lab concept introduces some technical problems for AT. A few examples of this are; speech recognition input and screen reader output over remote desktop. (RDP requires an additional license for JAWS)<br>
<br>
Generally speaking, the best way to avoid licensing agreement issues is to use a network licensing system. Freedom Scientific has a licensing server that works with JAWS, MaGic, and WYNN. Other vendors have similar offerings but it is always best to ask the software companies you work with about licensing.<br>

Kenneth,<br>
At Metro State , we have been currently experiencing and piloting VDI for our users, for a while ( 1300 student registered with our services)<br>
Currently through Microsoft architecture/RD2 servers /HyperV module/Active directory/ SharePoint etc.. to provide alternative access to our physical computer labs : 900 PC - 300 dual boot I mac image ( 38 ADA stations= 18 specialized stations)<br>
<br>
<br>
- Our planning started with purchasing Campus/site licensing or concurrent where applicable.( you server team can contact each company software developer for their policy, found out contacting sales/admin is not a time beneficial if you are an IT guy like me)<br>
<br>
- Currently our VDI consist of I.E/Firefox, Office(including one note), Adobe Pro, Omni Page 17 Jaws, Read &write gold & Dragon ( still can't get Zoom text to work properly not only as software but as company as well) on Windows 7 image.( where users at home can login with XP through hyperV)<br>
<br>
- Our primary Goal is to provide Accessible user interface for our Print disable students and provide accessible online class management through Blackboard as well as our SunGard banner system. Our second phase ( we are currently testing) either to go with HI software or Fireyes installed for our Blackboard/Metro Connect servers/Web servers for Audit/evaluation/repair tool for Campus compliance.<br>
<br>
<br>
To answer your question my best suggestion is to plan purchasing software's can have multiple features and flexible with remote services ( Kurzweil and Don Johnston are not there yet) like Read&write gold<br>
Lesser the software's in your image is easier to handle and fix any issues such as drivers etc., another critical part is to prepare accessible templates and splash screens for user rights and specs when they are logging to your system.<br>
I hope this helps and if you have questions please contact me for specific areas.<br>
