I'm not sure I understand this.  At best, ATS can give you back a list
of IPs.  How do you decide which one to check against the exports?

In a pure IP world, every packet from a multihomed client carries a
source IP address.  So a server can use getpeername() to determine
which address a client is connecting from.  This is fundamentally
different from ATS.
