Hum, it would be infinitely more convenient, for deployment purposes, not to 
touch the driver at all. What I can do maybe is to hack the driver with 
reflection, since private fields can be accessed as well (except in applets).

Since you've done it before, would you mind sharing the caveats you went 
through, general warnings and also the particular class where the receiving 
InputStream for the ResultSet is? That would save a lot of time!

Also, the ability to monitor the amount of bytes loaded would be an nice 
addition to the driver itself. Perhaps a small Monitor class that extends 
Thread, which monitors the receiving InputStream and provides a single 
getLoadedBytes() method?

Thanks for your insight Nicholas.

Albert
