I'd like to see this commercial directory in action AND offered as a plugin. (ASAP)
I run a free noncomercial site and am getting fed up with people joining just to promote their products at my expense.
My sites grown to the extent that it needs more disk space/ bandwidth and needs to move out of a shared server, and the above could be a way to make it self-supportive without degrading the non commercial appearance of the forums.

I'm sure there would be others who'd be interested in having a separate directory to redirect commercial interests plus use this as a way to help pay for operating costs.
