I have heard of it being done with REALY good chroma keying... but that seems like it would be rather... aggravating?

You mean like this?

Compositing and motion control, in this case.

Read up on green-screening and motion control (if the camera was moving)

there are some great "how this was done" vids you can download here - including the "shots of mixed film speeds" section

no, rotoscoping is the aggravating one.

Read up on green screening, rotoscoping, chroma keying, compositing and punctuation.

After-effects, Shake, Flame etc... are programs to read up on.

Have you ever played around with masks and layers in photoshop ?

The link I gave for motion control will still be helpful as the movies show the compositing process in action (just pretend the camera isn't moving).

Also we are making an assumption you know how to achieve speed effects in camera in the first place - do you know about over and undercranking ? what about shutter angles for more or less motion blur ?

You will find you get more help if you are specific and less broad with your queries ...
