Interesting that I have someone who donated some code not long ago to handle
this. In v4 I planned on making this a standard feature of IBO. Is all you
would do is set a property, pool connection handles to true.

I'd like to see the code myself. Feel free to just implement right into
IBO's code and send me the modified files to consider for inclusion. I take
the best of each of your ideas and put my own little twist on it if
necessary and make it happen.

Trustware in action...
