Interesting. So if this machine was operational, I could travel back from next week to today to play guitar with myself in my own lounge room. Well that would be strange. But, how does that get me, in the blink of an eye, playing with other TGers in their lounge rooms ? Perhaps they could travel from my lounge room next week to play with me today... Hell, I'll wait til next week then... B)

Keep looking. I'm sure the solution is out there.
