I now have a serial-cable digital camera for which I bought a 64MB
smartmedia card.  Could I run linux from this camera somehow over the
serial cable (could it be slower than running from zip disk?)
or at least from a USB card reader if I got one of those?

We also have a 10MB CF memory card and PCMCIA adaptor - could BL3 (with
fs.img reduced from 20MB to 10MB) be run from that in someone else's
laptop computer, booting from a boot floppy disk?
