closed source drivers of any kind on a server = epic fail

One of the key kernel/module parameters people fail to use on dom0 would 
be max_loop=.  Ideally people should do something like:

modprobe loop max_loop=255

It really sucks when you hit the default limit (I think 8?) and you've got 
a bunch of live guests running ...

If RoR was built by "real Unix people" (tm), why would the platform 
matter ?

Web developer groupthink mentality scares me.
