And although what I'm asking about isn't what Maltaannon did, it seems like I might be able to use the basic technique - the time difference effect in conjunction with some other effects to get a fairly decent matte on a person walking.
Can anyone give me some pointers or advice about this? Has anyone learned the hard way that this will most likely not work (or will it?) And of course, if someone's done it can you give me a rundown of how you did (or hopefully point me towards a tutorial.)

it seems like it should work, .... however you may be able to get even tighter junk mattes with aharon rabinowitz's super tight junk mattes technique described in his tutorial....

No, you got it right.
Y'know, everybody's searching for a painless way of isolating a moving subject from its background that doesn't involve rotoscoping or chroma key. It's like the quest for the Holy Grail. So far, the search has been just as successful as the quest for the Holy Grail.
If you happen to stumble across the definitive answer, do check in: you'll be a very popular guy, and people you don't know will buy you drinks in bars.

Hello
i tried this a while ago with a stroke mask effect on a layer.
basically i had one composition in which i used a stroke to reveal a layer. then i brought that comp into another and used the time difference to catch the leading edge of the stroke effect. then i applied a cc radial fast blur and got a cool effect that caused it to look like it was being created by light.
