Please note that I am not spamming and I can't even verify if this is real or not but these guys (SEE EDIT) http://www.inkcityusa.com/Refill-Kit-For-Canon-IP4820-MG5120-MG5220-Cartridge-CLI-226-PGI-225.html
(SEE EDIT) Claim to have a working CIS system with ARC chips for the CLI-226 series cartridges. If they in fact have been able to engineer an ARC chip then resettable chips should be possible for these cartridges.
edit: After watching the video on that page it is clear that contrary to the item description they are just using the OEM chips.
Another question... how physically different are the CLI-221 and CLI-226 cartridges? For example; would it be possible to transplant a CLI-226 chip onto a CLI-221 cartridge and gain at least the visible ink reservoir window?
