Knapsack is a simple web service that takes a URL, pulls down the resource and all the resources it references, and 'compiles' them into a data URI. What's interesting about a data URI is that you can bookmark it and access it offline. This can be really useful if you have a device that has an intermittent net connection (an iPod Touch, for instance).
It works a lot like Hixie's Data URI Kitchen, but it preserves images, stylesheets and external javascript libraries.
You can install it on any web server that supports Rack.
