There is a company in Beverly Hills on Wilshire names SoHar that provides
a "template" for software and hardware fault tolerance.  They have
systems that use QNX & Solarias that I know of.  The QNX fault detection
to resolution time was in the 10s of ms.  They are good guys.  Give'em
a call if you are interested in this area.  I believe that they were
also available at myron@sohar.com.
