A number of vendors will be bringing multiple systems (either clients and/or servers) as part of interop testing and demonstration. Cryptsoft will have two servers running on two platforms (a C based server and a Java based server) and at least three clients (a C client, a Java client and a C# client). The interop diagram should indicate the number and nature of the servers and clients available to make it clearer what interoperability testing is being performed. I know last year we also had a couple of IBM TKLM implementations available and various vendors also showed connection through to off-site server systems. There is also a distinction between engineering prototype code and code that is shipping and production ready. That too I think should be clear to participants. Thanks, Tim.
