But that is a license requirement!   We need a mapping between IP address and callsign for legal use of IP on amateur radio....
(ID requirement)

   Not that I am aware of.  The IP traffic has NEVER required any callsign identification.  Nor has the TCP traffic.  Transmissions over the air are always carried atop layer 2, which is the AX.25 Link Layer protocol.  The transmitters on each end of every radio link use the callsign to identify each and every frame sent over the air.  Our callsigns are used in AX.25 Link Layer in the same way that MAC addresses are used in the 802.3 ethernet layer 2 / link layer protocol. Take a look at your ARP table to confirm this.

   The "transmitters" must be identified, and they may identify *within* the published protocol (in this case AX.25).  This is all that the FCC requires.
