Digital has spun off that group into Tracepoint Technologies
(http://www.tracepoint.com) - I believe their patent is
different. It's called "Binary Code Instrumentation" - the difference
being you instrument a linked executable, as opposed to instrumenting
unlinked object files as is the case with Purify.
