Canon flash?

Looking into a 'Dark Side' SLR - either Canon or Nikon.

I shoot a lot indoor, and the ISO flash shoe of Nikon seems a big plus to me. I also really like the D200 body.

However, the D30 (D40 by the time I'm buying?) is an interesting alternative, not in the least since Canon seems to have a better lens line-up. (Especially those white-painted red ringed lenses that are at least in financial reach).

One of the thinks I'd like to do with my camera is using of-camera flash using radio control. Pocket wizards seem the way to go but they need an ISO shoe.

What are the options to use radio-controlled flash systems using a Canon D30?
