actually this is an interesting point, and something ive thougt about for a year or so.
for example, if i live in Milton Keynes but have a job 50 miles away in oxford that is worth £100 per month, it would be great to swap this with work more local to me...
like for like swap... would save time, less expense etc etc
but the reality and the practical aspect of this and creating a system that works, would make this quite difficult to implement...
but really interesting if we could make something happen ie Swap Work
