Client JavaScript data storage

Cross-browser data storage made easy using PersistJS. It supports a lot of different ways of storing data on client browser, falling back to plain old cookies, when necessary. The library itself is really minimalistic and standalone (opposed to Dojo Storage, for example). Also, it can be integrated with another lightweight runtime storage solution called "Taffy DB", which will enable almost SQL-like queries in JavaScript. Looks very nice to store some user-related info, session data, etc.
