I would like to create a minimal bootable image for a USB drive (or other formats, maybe even floppies, but USB is the focus) that boots into a single application (in my case, a custom minimal word processor, although freeDOS EDIT is a decent start for what I want) to create a kind of "typewriter on a USB drive", that will work on any hardware you throw it at and provide an environment for writing in.
FreeDOS won't work on non-BIOS machines. Also, the ability to write-access the USB drive after boot is not guaranteed, depending on the exact BIOS implementation.
Since you say the target is to use "any hardware", I assume you have mostly current hardware in mind. Hence no, FreeDOS is probably not a very good choice in my opinion.
You mention that you plan to write the application yourself, and that you'd like it to boot as fast as possible. With such constraints, programming an UEFI (EFI PE) application might perhaps be a good (and challenging) choice.
