Some comments to the letter from Mr. Kwang Sung:

-OSI is not 'connection-oriented' although the connection-oriented 
protocols are the ones mostly used. There is an addendum to the 
basic reference model (ISO7498) where it is stated that one can perfectly
use a stack with only connectionless-mode protocols (although not all
protocols have been accepted as international standards).
-In ISODE you don't use TP4 over TCP but a small protocol equivalent to
TP0 and providing ISO/OSI Transport Service. This means TCP is treated
as a protocol providing a CONS (Connection-Oriented Network Service).
-My own experience tells me application gateways is not a realistic
solution to interoperability problems.
-TCP/IP is widely used in European research centers and universities.

OSI is interesting although it's efficiency problems must be taken
seriously. You may love OSI, but the real issue here is whether 
OSI loves you.
