greetings, I'm not sure about the quattro card, but you should be able to find other bt8x8-based cards with multiple inputs (I'm not extremely familiar with model names and so forth, but I do use a PC/104+ bt8x8 card with 4 inputs, so I'm sure similar cards exist for PCI). These cards typically mux the video inputs, so you can't capture from multiple sources simultaneously, though you can rapidly switch back and forth between the inputs and get a reasonable frame rate. Though what's reasonable for me might not be reasonable for you, of course. If you want to maximize the frame rate on a single card, then you need to synchronize the signals of the various inputs.
As for using multiple cards in one system, I'm fairly certain that the bttv driver can share interrupts, so irq availability may not be as much of an issue as you think.
