fruux Available in Version 0.6

Last February we were reporting about the initiative of our German friends at fruux, aiming to release a "true social networking application" allowing you, at home or on the move, to keep track of your contacts at a mouse click.
fruux v0.6 was just released and is now in public beta. The social features are not yet implemented, but in it's current state fruux is already a nice (and now publicly available) alternative to MobileMe's sync functionality. The sync features, which allow syncing multiple Macs via the "fruux cloud", are described here: http://blog.fruux.com/2007/10/20/synchronize-multiple-devices/
We also gathered some info about their roadmap:

We hope to release v0.7 (including calendar and maybe bookmark syncing) very soon. When our basic sync features (address book, calendar, bookmarks and maybe preferences) are ready (probably around v1.0), we'll start rolling out our so-called "social sync" features which are described here: http://blog.fruux.com/2007/11/18/sync-with-your-contacts/
Our current v0.6 delivers the necessary foundation to speed up development and additionally allows interested users to simply download our client and sign up themselves via the client.

The integration of their planned social-syncing would transform fruux into an interesting hybrid of Apples MobileMe and Plaxo.
