Here is a fun thing I got to work: CloudPilot doing a network HotSync via a proxy server to a modern sync client running on Linux (palm-sync, written in TypeScript, which makes writing new custom Conduits a ton easier!).
The urge to now port this to Go and write a little Evolution → Palm sync client ... and maybe some new palmOS apps for syncing e.g. Fediverse (like https://gitub.com/knickish/heffalump by @knickish) and Matrix chats to it!
My Handspring Visor now has a 56k modem Springboard on its way :)
