Network enabled SD card project wanted.

Present a decently fast FAT (or whatever the multi-gig evolution was) filesystem as an SD card, and have the other end of that connection be a samba or other remotely mounted filesystem.
Who is with me...

There is already https://www.toshiba-memory.com/products/toshiba-wireless-sd-cards-flashair-w-04/ and a couple other manufacturers.
The SD card contains a hotspot, powered by a camera it can be accessed remotely to download photos... ;-)

This might give you a head start to tinker with:

If you want to a networked block device then nbd is vastly more efficient than trying to talk SMB which is a nasty complicated old protocol. It's not as if you could easily use samba to provide anything but a file pretending to be a block device. There's not enough info to fake a FAT fs efficiently.
The other protocol that was cool but never made it mainstream because it's simple but not fast enough for data centre with AoE (ATA over Ethernet) which is basically a way of talking to a CF card or hard disk over ethernet (or other network) with very simple (microcontroller grade) protocols.

How it would differ from toshiba flashair? https://www.occitek.com/toshiba/memory-cards/flashair-w-04-wireless-sd-card/

The system having the card plugged into expects to have exclusive access rights on it and that it's structure will not change except it self is doing it. Mapping all sectors of a SD card wirelessly to blocks on a server (like a Linux network block device) would be doable but accessing it conflict free by more than one writer... let's answer someone else:
