Here is a link to the post that contains the work I did with the Catalyst socket object:
http://www.kixtart.org/board/ultimatebb.php?ubb=get_topic;f=2;t=002291#000000

That's as far as I got, and I decided that it was not going to be useful enough to put any more work into - I switched back to 'C' coding where I needed network access.

The frame-work is all there, but remember that you will not at any stage be able to pass binary data reliably.

Also don't forget that the work is now 2 years old - KiXtart has moved on a lot since then. Ben Dulaney has done some work porting to the newer version of KiXtart and using KiXforms.
