Okay!  I agree that the appropriate place to set the flag 
is in the TCP header.  Passing state information about the link 
(i.e. low BER, etc.) to the transport layer makes perfect sense. 
This state information is loosely-coupling the layers (worst
case) and only marginally violates any end-to-end religious
cannons.             
Which lends to the next question:  How many competing TCP algorithms
using FEC information are in the community today?  Is there a
short laundry list?
