Jon - I have decided, at the suggestion of one of our Mudcatters, to develop these ideas and write up a more detailed description, including tuning notes and chord charts. I think that's a great idea, and will do so within the next two/three weeks. BUT;

The Nashville tuning essentially uses the octave strings of a 12 string guitar for the bottom four, and the normal strings for the top two. That is E,A,D,G on the bottom 4 as always but an octave higher - then the top two are normal. The sound helps a live band maximize the acoustic guitar sound with two acoustic rythym players.

I simply took that notion, and dropped some of the strings to an open D tuning D, A, D, F#, A, D. Again, with this sting configuration, the bottom four are an octave higher than would be normal, but of course, fingered in the same manner as you would in this tuning.

I have played with this tuning (normal strings, though) for years, so I am used to it. I will spend some time writing up a better description and post it. I think other folks will like this set-up, too.
