XMarks has a version that lets you run your own sync service (WebDav or FTP, IIRC). That only covers bookmarks though.

Paranoia or convenience. Take your pick. You can't really have both.

I didn't know that, that's awesome and definitely worth further consideration. Thanks for the information!

IIRC, Mozilla Weave (now Firefox Sync) encrypts all of your data on your PC before uploading it to a webdav share- Either your own, or theirs.

If you use your machine, they never see it, and if you use theirs, they can't decrypt it.

[logic]

Weave is about the only thing I really miss since switching to Chrome; I ran my own server, but encrypting the data prior to transmission meant I wouldn't have felt terrible about sending it to them. Architecturally, I felt pretty good about it.

Chrome's syncing? Not so much.
