browser integration?

That's a major down side and one without a good solution. Pherhaps you could try clipperz.com; they offer a standalone version you can self host (haven't tried it yet).

Ultimately the solution to this has got to be a FOSS online password manager with a slew of nice features (two factor auth, various integration, etc) so that I don't have to trust a third party host and get a network-accessible password safe.
