@h3artbl33d We use KeePass with the database on one of the NAS systems.
De database is included in the daily backups to our online storage, two different, and also just synchronised to the online storage.
The desktops connect direct on the NAS.
The netbooks and Ububtu laptop have a local copy, synchronised with the NAS.
The mobiles connect to the NAS using WebDAV.
I think we're covered.
