I am a little late to the party, but since it is still alpha-
two things that would impress me would be if:
1. Have the members searchable in a dating site format if possible, i.e. by gender or some variable.

2. Have adsense ready banner placement that WON'T get you banned from adsense. By this I mean not only placement, but disable the showing of adsense banners to the administrators. I had modified my osdate script in this fashion when i realized that while moderating all new users for see more approval i was also viewing adsense ads (something that will get you banned from adsense).

These two features "built in" to the core of trident would seem to be very good features to add to the list when selling it to your new customers. imho
