FWIW, a PCMCIA camera has *TONS* more bandwidth and *TONS* less interrupt load than the ISA bus (which is what the PCMCIA bus essentially is). We used a parallel port camera for awhile, but the performance and load on the system became so bad that we were forced to switch to a PCMCIA camera, which works much nicer. (Note, this is under Win95, but the hardware issues are the same as in FreeBSD.) The PCMCIA bus has all the bandwidth you need, and the new CardBus stuff (not supported in FreeBSD) has even more, being 'pluggable' PCI as compared to ISA.
