So let's change it slightly: Ethernet is not designed for huge
broadcast domains.
How big is huge? To some degree it depends on how broadcast "chatty"
the protocols used are - but there's also the matter of having a
size which makes it possible to troubleshoot. Personally I'd prefer
an upper limit of a few hundred computers.
