The other potential advantage zip might have is if you could boot from it, which might make the need for floppies a little less urgent.
Not long ago we had threads about installing internal Zip 100 drives into Compact Macs set up so as to not eject media at shutdown. They were used as replacements for the slow, anemic 20MB-80MB HDDs shipping in that era.
Later we moved on to using modern 2.5" SCA Server HDDs as monstrously oversized HDDs for Macs in the II series and Quadras.
Now we're moving on to SCSI-SD and SSD solutions. Storage solutions both fixed and portable evolve, even in time capsule environments like ours.
p.s. unless your machines are mostly in a permanent setup, networking is a lot less convenient than SneakerNet over Zip, most especially so for the old Compacts or the IIsi where NIC pricing is prohibitive. With Zip you just rock and roll. PhoneNet just trundles along, but it was WAY cool back in its time.
