ok - - - I'm going to give that a try.   I know how to get Rev to listen to 
ports, but I'm a little rusty on the 127.0.0.1 technique on the javascript 
side.   

So if I have Rev listening to 127.0.0.1 port 1986, and I don't want the ahref 
to go to a new page, is the only way to accomplish this to create an 
invisible iFrame with a different target name?

<a href="127.0.0.1:1986" target="invisibleframe">Click me to talk to Rev</a>

That type of thing?
