A MAC address can be spoofed MUCH more easily than an IP, like ADDiCT mentionned. Any user can change his MAC address as he see fit.
My cable modem get my NIC's MAC adress and if i change of MAC internet doesn't work anymore (I have to call my provider to ask resetting modem). And less people know MAC spoofing than IP Spoofing

ioFTPD doesn't have any idea what the MAC address of the client is. io deals with TCP/IP, not raw ethernet packets. Having it dwelve lower in protocols would require more resource, not less.
it will require more resource only on connecting. That's not a problem. I don't think there are not lots of people connecting to a ftp at the same time. If yes, it's not a problem because computers have enough ressource to do it.
