Don,

I think this frame has something similar to what you are talking about for lugged drop outs.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ru=http%3A%2F%2Fsearch.ebay.com%3A80%2Fsearch%2Fsearch.dll%3Ffrom%3DR40%26satitle%3D7239558444%26fvi%3D1&item=7239558444&rd=1

These have been available for quite some time, however I think they are just really ugly. May require less of the builder's time, but still ugly.

The way a framebuilder melds the drops to the frame has always been one of my favorite details on a frame. The plug in drops just don't do it for me.
