Previously, I was the customer & community guy for the Web Platform & Tools Group (IIS and ASP.NET) and was a Sr. Consultant for MCS in Philadelphia.
Before Microsoft, I was a consultant with DEC and prior to that an Engineer at W.L. Gore (where Gore Tex® is made)
Digital's research group built a pilot of VMS running on Mach but never took it to production. Having been written in the proprietary BLISS language, it would have been far too difficult to make the port.
