Dodged that bullet I guess. ;)
Pre·RHEL Red Hat was also being used in scientific/research contexts.
I had a 20 node Pentium 4 Beowulf cluster built using RH7.2 which very soon ticked a few unfortunate boxes.
64 bit hardware (and the large virtual address spaces) were needed for most applications which, until the Opterons arrived and were affordable, meant 64 bit Unix boxes were still desirable.
DEC had a version of RH7.2 that ran on some of their Alpha workstations which worked but I found slower the Digital Unix 4 (OSF/1.)
I imagine once IBM decides that RHEL is just a platform to run their proprietary software and services they might decide it is cheaper to outsource the development and maintenance of the boring FOSS components to the RHELatives.
I definitely wouldn't say there is nothing cheap about IBM but rather in common with most US enterprises, there is everything cheap about IBM.
