I don't know if it is even feasible, but if you don't ask... :)

I much prefer hosting my own Sync server, as I value privacy, and like
to maintain control of my own stuff.

Once upon a time, there was a Bookmarks Sync Addon called ... XMarks, I
think it was. Yes, XMarks. I loved that Addon.

It had an option for syncing to your own WebDAV or even an FTP server. I
used the FTP option, and it was a perfect multi-way sync (I had 3
computers syncing). I never had a problem with file corruption, but I
also most likely never 2-way sync'd from 2 or more devices at the same
time. I'm pretty sure the files stored on the FTP server were JSON files.

Anyway, I would love love love to see an option to do this with TBSync.
