I spent a month about two years ago to create packed.it, which has been used by few developers, which cannot compete with other known application even if it is absolutely unique.
Right now it is not even working with FireFox, just IE7 and few other browsers ... the reason? No time to update it, and low interests from Web community.
So what's next? I have no idea, but if you are interested, packed.it domain is gonna be free soon, and my service is gonna be down soon as well.
Thanks to those developers who believed in packed.it and used it for some project :)
