Multiple SSPR Portals?

Hi,

Is it possible to have different SSPR Portals in the same FIM deployment?

For example, one SSPR Portal for staff, where they would require the FIM client and be presented with one set of SSPR Questions.

And another SSPR Portal for students, where they dont need the FIM client, and be presented with a completely different set of SSPR Questions? Perhaps running on a different URL to the staff Portal?

lastly, is there something about an internal (intranet) vs external (Internet facing) SSPR Portal capability?

thank you,

SK
