TCL was the language used with F5's BigIP for writing custom rules on their load balancer. I' haven't used BigIP in years, so I'm not sure if they still do.
This was the last big thing I wrote in TCL and I still use it to this day:
TCL is a neat language, but these days if I need scripts, I'll usually turn to python or ruby, plus they have a lot of libraries and packages. Like others have said, it's used in a lot of stuff where you need to embed a scripting language for extensions, similar to Lua.
