Not everyone slaps "Broker_" in front of their addons, which is awesome and cool, but not all addon sites are equal in their categorization of addons either.
I'd like to keep Tek's wiki list as up to date as I can...well just because I like it. If people notice any LDB addons missing from the list, could they pop a link to it up here? Particularly those addons that have creative names outside of the 'Broker_' convention, and therefore harder to search for, unless you know what you're looking for to begin with.
By adding standalone addons that also provide an LDB feed you are opening a huge can of worms, IMO. Unless you are dedicated enough to catch them all out there (there are tons by now), and keep the list updated (that's the deal breaker here) at which case I must really salute you.
