Most of the browsers these days allow you to store a lot of data instead of using cookies. I am still trying to make a library which will allow you to store data on the browser no matter if you have localStorage, globalStorage, flash or the good old cookies. The thing about using flash is that you need to wait for it to initilise and that is a little bit of a problem. I hope to release the library under the BSD license. Not sure if anyone would be interested, but I really need to get it done for fefoo .
