Still i don't really think that this would work, it won't really make them stop stealing the info, specially since they could just go and rent internet for an hour or so and steal the info from there, they are pretty cheap (probably a dollar or less an hour, depending on the place), so sure, it makes it harder, but only a bit.
And having the applications needed in any computer isn't really a problem, since there are a lot of aplications made portable and the usb sticks are really really cheap.
I would say that it's more a problem than a solution, but i have to agree that there's no reason to use a proxy to enter the wiki.
Probably you should also check things like software that allows to download a whole site, or people that access more than 'n' articles or downloads 'n' from the wiki a day or in a range of time.
