Custom build of $.Deferred, $.Callback, $.ajax

Custom build of $.Deferred, $.Callback, $.ajax

I'd really like to just have these from jQuery. No Sizzle, dimensions, etc. Anyone know how to do this? I haven't found an independent library or libraries that combine promises with ajax and treat deferred resolution as jQuery does (a non-promise value treated the same as a resolved promise). Anyone have ideas? Thank you!
