We have several customers using NumXL on various virtual server architecture, including, but not limited to, Xen, XenServer and VMWare.

The license key is restricted by the machine or the server. As a result, you'd need one license key per server, regardless of how many concurrent users CITRIX sessions you may have.

Off course, bear in mind, the overall performance of Excel and NumXL degrades with the number of the active CITRIX sessions.
