Can you be more specific about monetization links? What form would you like to see this take? We do offer the ability to commercially license your controls via our site (e.g. you could dual-license your control and offer commercial support for a fee).
License type: totally 100% manual right now. When the repo is first added to Cocoa Controls, a field is filled out for specifying which licenses the control is made available under. This information may get out of date as time passes (I've seen many instances where a developer changes from GPL -> MIT or Apache 2.0, e.g.).
I actually asked GitHub to make license a first class piece of repository metadata a few weeks ago, but no clue when or if this will ever be added.
