I can't wait to see this done!

Would it be possible to add a business directory layer to Dolphin 7.0?

My community is very large and I want the members to use all services the site provides for free. To make this possible I want my dolphin driven site supported by the local business to this communty! And there around 200 of them!

So my idea is that business's could choose from (x) amount of listing styles tailored by site owner.

For example:

[Basic Listing]
-feature, feature, feature
[Intermediate see more Listing]
-feature, feature, feature
[Advanced Listing]
-feature, feature, feature
[Premium]
-feature
-subdomain with compact dolphin toolbar at top? (ie. business.domain.com)

And business's could advertise events, post ads to areas (defined by site) owner throughout the site (member login, main site banner / wall, section etc)

I know directory scripts suck, I agree but this would be an amazing option for social working sites that want this feature as say an addin module or something. Personally I will need this desperately to make my community business driven site happen!

Feedback and response is greatly appreciated by both boonex and the member community (ps. I have researched a lot of social networking sites, php directory listings sites so I am confident dolphin is the right direction for me!)
