OK, currently we have NAM 4.1/4.2 that front-ends a Citrix Web Interface. The Web Interface also interfaces with the Citrix Secure Gateway (but the CSG isn't front-ended by NAM).

Basically just using NAM to do the SSO for internal/external users to the WI and then the WI does what it needs to do with the CSG And all that good stuff.

However, Citrix is replacing CSG/WI with NetScaler and Storefront.

Does anyone use NAM with the two aforementioned products?

Citrix of course, doesn't know/care.
From what I can tell, Citrix would prefer you use NetScaler rather than NAM for the reverse proxy, but I don't believe it does eDirectory auth, or expired password detection, etc.

But I could be wrong.
