client ext script example

Hi,

Been trying to get a external script running with a hobbit client and
a hobbit server.

The script runs on the client and I just want it to take the data it
gets from the script and create a new column on the server with the output in that alert.

The script only needs to be run for this one application on the
hobbit client, can't be run on the server.

Does anyone have a short howto or a very simple client side script
that they can post so I have a working model to tweak?

Thanks,

Lee
