You know, I've been wondering why people drill holes at all.
How about SMDIP (Surface mount DIP) instead of SMT?
I.e. design your board so that the components mount on the
trace side of the board. To mount DIPs, bend the legs out 90 degrees
and solder it down like a surface mount device. You would have to adjust
the width between the rows of pads to account for the extra width. Using
Eagle's Offset Pads would probably do the trick. You can also surface
mount normal, visible, passive components. Drill holes for connectors
and things that need physical strength. You could probably do double
sided boards like this, even with components on both sides.
Drilling the vias, of course.

JJ
