I've held my tongue this far, but can't let this pass.  Our OCS
servers will not work with IBM's TCP/IP implementation.  We have
our own implementations of telnet, ftp, and smtp (to profs or snads)
which work over our OCS servers.  Needless to say we feel that our
products will outperform IBM's and they definitely utilize far fewer
mainframe resources than IBM's.  (Amazing how the IBM's lined up)  
I believe that you will find that the resource impact of IBM's TCP
is significantly more that you would believe from David's response.
