Theoriticially it could work with 50 or more remotes at the same time. The developer site has all the code needed to recieve and understand the existing Kenwood remote. By what I remember, the code for IR is in the kernel, so all someone would need to do is download the kernel source from the empeg site, and add the new codes for /dev/ir and output the correct codes for the player software to pick up on. Then an .upgrade file can be released that only updates the player kernel, similar to the button fix patches.
