dvcs-autosync is a project to create an open source replacement for Dropbox/Wuala/Box.net/etc. based on distributed version control systems (DVCS). It offers nearly instantaneous mutual updates when a file is added or changed on one side but with the added benefit of (local, distributed) versioning and that it does not rely on a centralized service provider, but can be used with any DVCS hosting option including a completely separate server - your data remains your own.
