There are lot's of technical issues with CFL's: power factor, harmonics, inrush, RF emissions. These can all be solved. I can imagine a zero-mercury, electrodeless, CFL that looks like a resistive load to the line, has a nice spectrum, is dimmable.... It will probably cost more than a dollar or two, but the first CFL's I ever bought cost about $25 and had to be ordered from Real Goods.....
