Motorola has hundreds, or likely thousands, of Tcl coders.
All (?!) Motorola semiconductor fabrication facilities are
...
individual workstations ...
GEM ...
recipes coded in Tcl.

I work in the Secure Design Center (part of CGISS [http://www.motorola.com/cgiss/]) 
and maintain an automated test tool based on Tcl for our group.

Our test tool incorporates dlls which support des and aes
algorithms as well as dlls for accessing some SCSI and cPCI
buses. The test tool includes things like generators/parsers
for message standards, etc.

This test platform forms the basis for our factory programmer, which
downloads the code, algorithms, and radio parameters into our chips.

We also use a modified version of this test platform as an encryption
server. People in our lab and around the country connect to it so that
we can share the limited hardware resources on that computer for testing.

I like pictures, so here's a diagram:

         +-----------+                     +---------+
         |  Tcl Test |     physical layer  |device   |
         |            ====data, commands=== under    |
         | Platform  | sent via rs232, NIC,|test     |
         +-----------+ SCSI, cPCI          +---------+

I don't have metrics to show the impact of using the test tool, but I can
try to dig some up and post them here if possible.
