Server bandwidth is rarely the limiting issue these days. In any case,
bandwidth desn't limit users in the sense of there being a maximum it
can sustain - all it does is make the site appear slower when the pipe
is full. If you're genuinely concerned about that, then reduce the
size of your pages - 450k is too big, you should be aiming at a
maximum of around 150k (and less for the home page).
A more likely problem, if your site is popular, will be the ability of
the server to cope with the necessary number of simultaneous
connections. Whether you can do anything about that depends on the
type of hosting you're using.
For comparison, I look after a site which is one of the most popular
in its field (Google PR of 6, Alexa rank of around 80,000). That has a
2Mb connection to the outside world, and that's never been a limiting
factor. The biggest bottleneck on the site is the MySQL server, which
has trouble meeting demand.
