Archiving Software

Well, I didn't get any replies to my question about how best to archive Cromemco software, so let me ask again in broader terms: Aside from bootable system disks, for which Dave Dunfield's imaging program seems to be a much better solution than Teledisk, what's the best way to archive software in a way that makes it as universally useable as possible and downloadable/emailable? For example, I have original distribution diskettes for CP/M Wordstar, Supercalc, etc. on 8" disks. Obviously images wouldn't be very useful for someone with only 5" drives or no 8" drive on the PC; on the other hand, a DOS ZIP file of the files on that disk would have to be copied/converted back to a CP/M format disk somehow. So, how are the rest of you dealing with this? TIA, m
