It's not so much the bandwidth as it is that you'll quite likely be
dominating usage of memory on the server.

Java tends to be a RAM-hog, particularly as you progress to using J2EE
and other "heavyweight frameworky" sorts of things.

Nothing.

The difference is essentially that with "plain old web hosting" where
you're serving static files and *possibly* running a bit of
Perl/Python/PHP is something where 15 clients could, in principle,
share the same server.

In contrast, it isn't tough to get to the point where traffic dictates
having multiple Java application servers...
