OS X Command-Line Vieo Capture

I need to capture full-size/framerate DV + audio from a firewire source on OS X. That's the easy part. Controlling it from a script is the hard part. If this were Linux I'd use ffmpeg, but it isn't...

Here's the story: I want to write an app for a kiosk-type environment that'll allow a user to press a key to start recording and another to stop, at which point he/she will be presented with a dialog asking for some information about the clip, which will be entered into a remote database via an XML RPC call. The back-end already exists and I'm working on the front-end in Java (which I know very well), but Java can't push the bits around fast enough to do full-framerate capture. I was originally planning to use objc/Cocoa, but Cocoa is a bit insane to try to learn in rapid crunchtime. I already know how to issue local commands via Java, so, here I am.
Ideally I'd like to be able to specify a filename and format in advance and start the command, then issue some other character to the console to quit recording and save. Any idea what software I should be looking at? I know I could use iMovie and AppleScript, but I worry that's getting into insane levels of complexity. If it's the only solution I'll try it..
I'm also open to other suggestions, or if anyone knows of an objc framework that makes interacting with Quicktime Sequence Grabbers less of a pain (yes, I know QTKit Capture is coming in 10.5, but that'll be a couple of more months..)
