I am researching 2X RAS to see if it will be suitable as a replacement for our XenApp server. I have two questions about 2X RAS(current version and future plans): Is there a way to limit a published application so that there may only be a single instance running? Is there an API that one could use to script things with Python or VBscript? We have a need to be able to query and see which applications are in use, by whom, and for how long.
