Multiple incoming requests from unknown clients

"different authentication methods" I really mean different user data stores
and different methods like an optional second factor. I can wrap everything
is a custom auth module, however I will still need a way to know which data
store to use.

I could use NAS, but that would require the client to declare their IP
address. I was hoping for a solution where the client IP is not known and
the right thing is done based on some attributes not cumbersome for a
client to supply.
