yes dmizen, thats who i meant!
where there's a will there's a way! eh
your right about tommy/tony, but many famous git players tune their gits down a semitone - Jim Hendrix/jeff beck/ SRV just to name a few - sometimes its for a distinctive sound, other times so they can use heavier gauge strings and still bend, its just easier to play with lower tension, bluesy sound, and for slide playin with heavier gauge string in standard tuning.
lots of these modern sliders use low down open c tuning a lot! ie Ben Harper/john butler
here's two fingered django!
