The TF hub does go into 'neutral' between its two gears, but as I understand it this should not be used as a freewheeling mode as it's difficult to re-engage a gear safely without coming to a halt.
Personally I don't think these fixed hubs are a good idea. First because the basic attraction of fixed is simplicity, and second because there is always quite a lot of backlash in the mechanism wnich makes it feel as though you have a slack chain.
I did use a TF for a disabled rider with some success, but really the main benefit over single fixed was that the rider (who only had one good leg) could put the hub into neutral when stationary in order to get the 'useful' leg into a good starting position.
I've no idea about converting an AW to fixed, excepting to say I wouldn't bother myself.
