Fairly okay.

There's some performance issues that I need to work on, but these are
unlikely to be noticeable unless you're running nbd-server for a whole
classroom of fairly modern x86 machines, or some such. And then still.

I doubt m68k machines will slow down because of NBD. The very first NBD
installation that I did was on quickstep, back when its SCSI driver was
still rather crap. It was faster over NBD than it was to local disk.
Running Debian/m68k was the reason why I started doing NBD in the first
place :-)

In my opinion, it's definitely a good idea.

The volume of a pizza of thickness a and radius z can be described by
the following formula:
