8 bit web devices on private network.
8 bit devices means the largest block of memory I can handle is 256 bytes, and the total memory I have is actually 2K. Which isn't enough to handle 256 bit encryption, let alone 4Kbit encryption keys.
I don't mind so much at home -- I've got service fast enough to handle the advertising download -- but for work this sucks donkey balls. And I've got 3rd world clients with 10yr-old PC's and 5yr-old phones.
