Here at CBER FDA we are using several flavours of TCP/IP:

- Trumpet Winsock (shareware), QVT/net (shareware) + other winsock apps.
  This is a great way to get TCP/IP on your machine for a nominal fee. 
  The winsock is the TCP/IP "engine" providing services to any winsock 
  "compliant" application. Many of these are free, like NCSA Mosaic, 
  PC Eudora, GopherBook, etc.

- FTP Software's PC/TCP (DOS-based) and ONnet (Windows). Not much 
  experience with these, but the NIH supports both of these products, and 
  they seem to do a good job. A single user copy of ONnet is ~ $400 US

- ST 420, a client-server implementation of TCP/IP  where most of 
  the protocol software gets loaded from the server (on demand). This is 
  starting to be delivered here, with no apparent success so far.

My $0.02 worth: Go to TCP/IP. Patworks relies on DECnet, a protocol that 
models itself after the OSI model. This is a great educational model, but 
it was DOA as a real implementation. (Especially now that the US 
government dropped its GOSIP proposal).
