Don't use webrick for any serious hosting - sending out a 700mb file
constitutes serious hosting.

I'd say your best approach would be to setup a mongrel cluster running
behind apache and then either a:

a) let apache serve the file and never hit ruby code

or

b) install mod_x_sendfile into apache and just have your code set the
appropriate header to let apache do the lifting.

You could also do the same thing behind lighttpd. There's many howtos
about on lighttpd+mongrel and apache+mongrel - google about.
