Dear Andrew

	Yes, EPICS is still a fundamental part of our control systems. We had far 
too small a staff to write our own system.We benefited from the hard work of 
the EPICS collaboration in helping us move this technology from VME VxWorks 
to Linux, and supporting our abuses of it (~200,000 channels).

We hope to give back as well in terms of "hard real-time” controls methods and 
some large scale state configuration tools, amongst others.

Thank you again for the congrats

	Keith Thorne (no relation to Kip)
