Title: Liquid cooling... (was RE: What is the limit? (was RE: multi-homing fixes))

Actually, the fluid referenced in the URL (Fluorinert) is used to cool some Crays. It is only manufactured by one maker, and only a few systems use it. There are actual liquid cooled Cray parts in the NSA museum near Ft Meade. Non-operational, of course, just like this post...
