We used Linux in a product before it had a network stack. We did need networking, and used KA9Q to do it. We also used rz / sz (zmodem protocol) for file transfer over phone lines. I recently integrated zmodem into an embedded system for firmware updates over a serial port- it's still very useful.
The performance of the floppy drive was terrible at first- a friend of mine and I added buffering, so that it could read a track at a time instead of block at time (which caused it to read only one block per disk rotation).
For the same project my friend created the generic SCSI driver that still exists today. It allowed us to connect a medical film scanner to Linux.
