Hmmmm. what if we just made a DIS/DVC downloadable "transfer" that you could print on your color printer using the transfer media and iron on to the lime green shirt of your choice? That would make it easy -- maybe make it so that folks could customize it with monikers or catchy phrases or "naughty" or whatever...allows folks to choose split-tail polo, or banded or unbanded sleeves, etc. on their own... We might have to pay some sort of fee to DIS or DVC (or just risk the pirating copyright repercussions! )
I bet Land's End or similar places carry lime green polos. You would want a flat-finish all-cotton shirt (not pique) for the best result.
About the color, though -- I thought lime green was the "DIS" color... not the DVC-DIS color. Not that I mind lime green -- stands out in a crowd -- but some folks get that Kermity feelin' and it's not easy bein' green for them, I guess!
