Will it be possible to run penDirector on Citrix XenApp?
Using XenApp will not work since XenApp (6.5 and earlier) doesn't support USB redirection.
Live Pen™ 1, Live Pen™ 2, penDirector, XenApp (6.5 and earlier)
Anoto partners that also are Citrix Gold Solution Advisor Partners can purchase the Base Kit for Citrix. The Base Kit for Citrix can be used to connect Live Pen™ 2 with XenApp (version 5.6-7.5).
