Scyld Beowulf in particular works well on an isolated network, but it
gets a bit more exciting on a non-isolated network. You might have
someone else on your non-isolated network running rarpd, and then your
Scyld nodes won't be able to boot.

Depends on your application, but if you don't have a switched network,
the answer is probably plain "yes".
The easiest way to get a Weekend Beowulf is to use a lab that is
internally switched and is isolated from the rest of the network, so
you know there aren't any rarpd's floating around. Sounds like that's
what you have in your art lab.
