I can only say from the Fedora side, that it is very complicated. IBM
does not donate mainframes in the same way they may donate PPC
hardware to a site. Where-ever the hardware is requires dedicated
resources (water cooling, extra power conditioning) and contracts with
IBM. The contracts seemed to be the longest time and I don't know what
it entailed as it is lawyer stuff. There was just a long time of "we
can't" then "oh we can but you will need to use this one system we
have in a far away location using these methods".
