I think Dar's got the best way.  Have the Rev stack accept connections on
some obscure port; then the browser can make http calls to it on that port.
If it's all running on the same machine, use the address 'localhost' or
'127.0.0.1'.  If you want to stay on the same page, you can use an iframe;
javascript (or even a simple link with a 'target' attribute) can change the
src of the iframe to the results of a call to Revolution.  Either you could
just use this to display the result to the user, or javascript could read
back the text from the iframe in order to further process it.
