iFCP fabric attachments

["Robert B. Harmon" <bharmon@entradanet.com>]

I think this is a very interesting proposal, storage gateways are
possible
at several different levels, great work.

 Section 3.3 says: 
    The gateway builds the store of N_PORT network addresses for
    external devices in the IP fabric by:

    a) Intercepting name service requests issued by directly-attached
       N_PORTs and redirecting them to the iSNS name server or,

    b) Intercepting incoming N_PORT login requests from external Fibre
       Channel devices.                             

Could you explain how this would work in the presence of existing
Fibre Channel SNS and master switch?

I noticed on your comparison of FCIP and iFCP that the SAN islands
contain no Switches or Hubs, N_PORTS are connected directly to iFCP 
devices. Is is possible under to have iFCP gateways and FC switches?
