Or just accept the fact that flashes are a tad different from spinning rust. Expecting a decent wear levelling on the cheap USB sticks and other forms of flash is plain unrealistic.
USB stick are a bit better than old 3.5" floppies were - if both are used with fat, minix, ext, etc. At least they don't die by lying in a dark drawer. But if you want them to last, your best bet is currently to use JFFS2 on them.
Of course, JFFS2 sucks performance-wise, so the end result currently is that USB sticks suck in some way, no matter what you try.
