I'm not sure how it can be done in eagle. In most any other layout
software you'd just define the padstack so it doesn't have a pad on
top where you can't solder. Since the pads in eagle are a separate
single layer that might be impossible for all I know. You might be
able to fake it by using SMD pads, but it would be one horrible
kludge, should fit right in with Eagle.
There's a list 'specially for Eagle, you might have more luck here:
eaglecad@yahoogroups.comRegarding soldering on top side, It's possible for turned sockets,
which expose a little of the metal, but tricky.

This is one reason why auto-routers have limitations; a lot of folks here do most or all of their layout manually. (Well -- manually as in telling the program where to put the trace; it's still a heck of a lot easier than the old press & stick manual process!)

This feels like a kludgy solution to me, but I have used it at the prototyping stage.
