Yes. I do tons of this with digital cameras (single images). It works ok.
I have some issues with dma buffering and isochronous mode. It works as
long as you play nice with the buffers... At 1280x960 we get 7.5 frames
per second (400 Mbit, which is the common speed) and pick the ones that
correspond to some distance criteria. Note that Apple's new laptop has an
800 Mbit firewire, and I have heard rumors of a 1600 mBit version in the
works. So, just when USB 2.0 caught up in speed, firewire jumped ahead.
As to digital video ('continuous' images), this should work as well. The
simplest application I have seen for it is called 'dvgrab', which is a
simple command line app to save the video stream. But there are many
ieee1394 video capture GUIs as well. Choose what suites your taste.
We wrote our own 'dcgrab' to provide a digital camera counterpart.

It tells all.
My only horror story is that ieee1394 storage devices do not work if your
kernel is compiled for SMP, but you only have one processor. It is a known
problem. You have been warned.
