For the record, Microsol Ltd, an international company with offices in 
Ireland and Australia, is using RTEMS as a base for our next generation 
of products.

These products as Remote Terminal Units that are used mainly by the
Electrical Utility Sector to control Electricity Networks.

Our products need to communicate using multiple standards based and
proprietary protocols.

Some of the reasons for choosing RTEMS were (in no particular order):

- Cost (including development tools and network stack)
( especially avoiding on-going royalties )
- "Compatibility" with existing RTOS
- Availability of source code of the kernel
- Good support of the Coldfire Processor (5307)
- The ability to put together a package that will enable
third parties to develop for our product

Joel Feel free to add this information to your application collection if 
you like (note: the main corporate web site makes no mention of RTEMS, yet!)

Best regards
