Actually, I've had a small business idea that I might as well throw at you...

Down Under, there are 3 or 4 companies offering wireless/mobile internet. They all make roughly the same claim about performance ("UP TO" 7.2 Mbps, actual performance may vary depending on blah blah blah.) One may be technically faster, but have so many subscribers in my area that it is overloaded. How can I tell?
So I just had to take a guess at which would would work best where I actually live (and any other places I frequent with my computer, which are few).

I would have given a goodly sum to have some techie bring one (or maybe four identical) computers to my house and simultaneously test all four rival networks and give me the data, so I can make an educated choice.

Just throwing the idea up, AFAIK you might not even have rival wireles internet providers or something. The business costs would be a few standardised computers, and subscriptions to the rival providers.
Hell, to be really smart, you work as an agent for all the rival providers and sign people up then and there. Install it for them. watch 'em surf.

Ok, you may now think of all the reasons it won't work.
