Yes, the fundamental design is probably quite different. We would need to find a way to run this on a tiddler after the normal processing. I don’t know what API globalrize offers, if there’s anything available besides just dropping the script on a page, but you would probably need to take advantage of whatever API it offers.
Unfortunately, I have no time soon to investigate, but if you’re interested, and if they do offer some sort of API to call on demand, then one of the techniques I discuss in Pretty fractions might help. (Sorry, it’s fairly technical.)
