@Logical_Error "use case" - I think of it as a general purpose MCU with some bonus security features. I personally am developing systems around it targeted at authentication tokens, but I don't mean that to be a box into which it is defined. The emphasis on open source means that everyone is invited to use it however they see fit. The intention is not for Xous to be a desktop replacement - the transition comparison is more like going from say, Zephyr or ThreadX to Xous. It's an embededd OS so the harder challenge is porting code from one ecosystem to another. Because we are Rust, we already don't have source-language compatibility that C-based OSes would have. So maybe the biggest ecosystem you could copy paste code out of is Tock, another Rust-based OS.
