I got one step further to handle dc 4.2 images in a better way by embedding libdc42 recommended by cheesestraws. Using this lib will make it possible to generate them. The lib is up and running!
And no LaPorta, you are not unique
I am also Mac focused, which are all having access to my network: The 68k machines, the G‘s and the newer ones. I am using AFP Shares, Zip-Drives, physical Floppies, FloppyEmu, SCSI2SD and a RaSCSI. And Basilisk and vMac as well - but it is not streamlined, not elegant and not intuitive.
There are so many corrupted disk images out there. Soooo many missing meta infos and res forks. Others are named in a confusing way. And a lot of sit files are created using modern versions - not the ones I am using on the 68k boxes. You have to try out a lot, use ResEdit, move files from machine to machine to machine.
I hope to provide a convenient way to interact with and feed the old macs to get more people using them. Not only for playing one or two games. That is what I am doing: Working on my (favorite) IIci; using it for tasks that it can do.
