this is a great argument if you've actually got a cluster which
has a single, fixed use. my world is a completely general HPC provider,
and we certainly can't pander to some single application's bug-compatibility
with a particular distro.
this is simply part of the cost that an end-user must bear
when choosing to invest in a commercial package. I think
such users all too frequently overlook this: yes, they get
something called "support", but that support drasticallly
limits where they can run the app.

FC is one of my favorate peeves - a whole industry where the standard
is so low that none of them actually interoperate. put commodity disks
in company X's SAN shelf! heavens to betsy! that's unsupported...
contrast this to a *real*, honest standard like ethernet, where everyone
really does expect nics/switches/packets/udp/tcp even nfs/cifs to just play
nice together. yes, there are occasional problems with some obscure corner
like Cisco 10/100 autonegotiation - but Cisco is an FC-esque vendor...
vendors love lock-in. ignorant or naive users don't notice lock-in.
certain categories of admins love lock-in because of the job security
that accrues from managing crappy fragile stuff. but as the computer
industry matures, more people are realizing that lock-in is the antithesis
to standardization. my only fear is that the legal/political profession
will continue riding the fallacy of "intellectual property".
that's a great analogy, that IP is like a huge, ongoing traffic disaster,
with the lawyers and politicians chasing the ambulances.
