Limiting ethanol damage to plastic tanks

I've recently become aware of the ethanol/gas tank problem, and after several hours of research on the computer, I've found out that finding accurate information on the subject is like trying to lasso a gust of wind. Here is what believe to be true at this point. I'd like some comments from those more knowledgable on the subject if possible, and I realize in turn that I may be able to help some less informed than myself. Here is what I believe to be true.....
The ethanol in gasoline starts to attract water probably as soon as it enters your gas tank. When the ethanol absorbs as much water as it can hold, the ethanol/water mixture falls to the bottom of the gas tank where the water begins to be absobed by the nylon gas tank. This water absorption is what causes the tank to change dimensions. This is where I run out of answers and need some more information, if it exists in a form that I can understand. My questions are as follows:
1. Does the gas have to reach the phase-separation state (water in bottom of tank) for the absorption proccess to begin?
2. If so, then wouldn't fresh gas treated with a quality non-alcohol fuel additive such as Stabil limit the damage?
3. Would installing a "T" in the fuel line with a drainage hose and shut-off valve to drain the gas from the tank be a paritial solution?
