Yeah - it can be quite nice to do that, both for security and speed. Hugh Daniel's done some work on making Unix run on systems with read-only root drives - there are some SCSI drives which support read-only mode again, and there are PCMCIA flash cards which have write-protect switches and look like disks to the OS, so you can set them up the way you want and then go to read-only.
Unix has been ported to memory only systems including the Palm OS (using virtual drives) but you can't do much with it at this point. http://ryeham.ee.ryerson.ca/uClinux/ "The Linux/Microcontroller project is a port of the Linux 2.0 to systems without a Memory Management Unit. At present, only Motorola MC68000 derivatives are supported. The first target system to sucessfully boot is the 3Com PalmPilot with a TRG SuperPilot Board and a custom boot loader they put together specifically for the Linux/PalmPilot port. Thanks guys!" DCF
