also: evolution has already produced a gliding mammal (flying squirrels),
and who's to say in a few more eons that flying mammals won't develop out of them as they develop lighter bones, faster metabolism, etc etc?
as far as 'non-birds with feathers' go, name any non-flying bird. they feathers' usefulness is not for flight, but insulation in that case.
