Probably a really stupid question

[ZenGum]

Actually, what I want is a "pre-load next" option.

Say I'm browsing lolcats, and it takes a good five or ten seconds to load each page. (I know, the tedium, hardly worth the bother, isn't it?) Then I spend maybe a minute giggling at each page, then load the next and wait.

I want an option that, as soon as one page has displayed, I can identify the next page, get it to download all that, but keep it on hold until I am done viewing the present page, then when I am ready, a single click and SHAZZAM! there is my next page all ready to display immediately, and I can order the subsequent page to pre-load.

Any of you code monkeys reckon you can hack that? UT, could you make money out of it?

ETA: or, um, maybe someone could tell me how many versions of it already exist.
