reciprocal link check for directory

Hello -

I really like the directory plugin but it has a glaring lack of feature fail - I think it would be very valuable to have something that gives the option to set a requirement for a reciprocal link to be in the directory. I also think it would be helpful to offer a features that make the reciprocal link either required or as an option that would provide a discount to the annual or one time charge as a percentage off set by the site admin all the way down to free listing with a reciprocal link exchanged.

If the feature is there please let me know as I managed to miss it..

Anyone else like this feature request?
