I dont think wetwiring is all that far off, I would jump at the chance to be able to sit in a chair and just "plug in"
but yes, as gandalf parker has stated - there are MASSIVE problems with people who cant control themselfs, hell we have enough couch potatos as it is!
the only way I can think of around that would be to have you strung up like a pupet and have you excersizing as you are 'playing' round in ciberspace...

and then there are problems like you had in the matrix, would you realy die if you died while you were in there?
I would not be suprised if that were the case, the brain is a powerfull thing and capable of deceving even itself.
