does it mean, that it will be possible to launch native (arm/arm64) raspberry-pi distro on virtual box?

Thank you for your question!

There are some benefits, among them:

• syncspirit is faster. According to my measurements it is able to sync linux sources tree folder for 2 mins vs 15 mins of syncing when using syncthing (that’s over a localhost, of course)
• syncspirit has a different UI. That’s matter of personal taste, of course, but I like to see the exact picture what is synchronized and what is not.
• syncspirit is able to run on more older software (i.e. from windows xp and up). Syncthing uses golang, and its software support is indirectly controlled by google (i.e. “artificial aging”); recent builds are running only on windows 10 and windows 11. Microsoft already dropped windows 10 support, so, I expect that in near future google will do the same.
• the long-term goal of syncspirit is to allow “selective sync” feature, which unlikely to be implemented by syncthing.
