[weblet] How can a webLet communicate with the hosting html page?

Had a look, I like your hack - great to know you can embed dynamically
generated stacks using a cgi / iRev script!

It's doing the server based roundtrip for the communication though - to get
a responsive Web2.0 type app you need to use Javascript on the client side.
We'll have to wait for revised version of the plugin for that - maybe with
luck we'll even get "do script as javaScript" for standalones as well :)
