He, I wasn't complaining... just mentioning it. Maybe my limitatios in 
english made it looks as a complain, but I far away of that feeling

Yes, I insist,  we can join our efforts, maybe we can collaborate not 
just testing but working on the design/devolopment of squeak side of 
the plugin.
This mini-driver intent to be capable to manage diferent backends such 
as ADO, OpenDBX, etc?
We can drive our design to match that plugin to.
Anyway I recoment you take a look at the design of OpenDBX, it is very 
easy and clear, and maybe, at least, a place of inspiration.
