2-factor atuhentication Pointsharp LTM/APM

Anyone have any experience with LTM/APM with Pointsharp as a 2-factor authentication webinterface?

Specifically in this case: 2. Add APM/LTM preferably without Citrix web interface but includding pointsharp. 1. decomission Citrix Secure Gateway with webinterface and Pointsharp.

But, any experience at all is welcome :)
