Like many folks, I can't get ethanol-free gas here. =( When I was in the shop the other day, I saw some "ethanol conditioner" and it piqued my curiosity.
As far as I know, it's only associated risk with 2-strokes is that it tends to be somewhat more explosive than gas, and can damage the engine if it concentrates in the bottom of the tank after sitting. (Bent pushrods on my dad's John Deere 3 times before we found out it was the ethanol)
I know ethanol has been discussed before, but would something like this prevent some of the problems that ethanol may pose? http://www.amazon.com/Lucas-SAFEGUAR...el+conditioner
