Dennis Parker
System Architect
PerformanceRetail Inc.

Using Tcl since 1994 to:

  * Build a distributed design validation tool for a distributed transaction management system
  * Build distributed management mechansims for serveral systems
  * Build a user support server product that supports 1.5 million simultaneous user connections
  * Lots of other tools, product components, etc

I love using Tcl, but I usually have had to do lots of C/C++ and Java in order to stay employed. 

I usually manage to build a lot of Tcl around the edges of these systems, however.
