moving time lapse shot--manual

You'd have to figure out your start and end points, the distance between the two, the time/frame duration, and then divide the distance into those steps. Mark it off, and move the camera accordingly.
That's assuming frame by frame.
If you're just recording straight video and speeding up in post, you could just set an interval for yourself to move the camera the required distance.
So if I'm doing a time-lapse that's 10 seconds of screen time (24fps), and takes place over 2 hours, and I want the camera to move 4 feet... that's a shot every 30 seconds, 240 shots, 48 inches/240 = .2 inches every shot.
....waiting for someone to point out giant errors in my math.

I was thinking more in terms of pans or tilts on a tripod. I have a nifty little camera, that kind of looks like a toy, a Brinno time lapse camera. I've been shooting my first feature for the past 8 months before I discovered this camera, and decided to incorporate it into the film.
The way it works is so simple, that any child could use this camera with ease. It shoots at HD resolution, but has no manual functions other than the time lapse features, which allows you to set the frame rate, and interval of recording. So say: 1 frame, every 1 second, played back at 30 frames a second. Or 1 frame every 1 second, played back at 15 frames a second (for a more choppy look).
There's a little blinking light that let's me know every time a frame is being recorded.
Given these parameters, how would I go about getting some awesome moving time lapse shots (i.e. Breaking Bad).

So, if there were 20 marks, and I wanted 40 frames, just split the distance between the marks and move it once a second.
What I've done with a time-lapse before, just to do a quick pan, and I know some people (without naming names...) have done this on bigger projects, but you shoot it on a DSLR with an intervalometer and at a larger resolution, then you do a "pan" or move in your editor.
Either way, without automated motion control (like kessler's revolution head) or something that you can make precise movements on, you kinda have to wing it.
Assuming I'm understanding correctly.

A motion control rig would be pretty nice... but expensive.

You choose how precise and tricky you want to be

You'll have really nice accel and decel ramps - basically a full keyframe/bezier profile editor.

Really hard stuff to do... Just make some device where you can measure distance and angles properly.... If you get a nice ide about it share it please.

With ingenuity, it should be possible to apply similar techniques to tracking shots-maybe mounting the cam on a toy railway carriage on tracks, with the carriage pulled along by string (the string being wound onto a spindle on the clockwork oven timer.) ie motion control on a tight budget!

- If you're going to do much of this, investing in a basic motor-control PCI plug-in computer card you can program would be easier than you think.
