So instead of running a process heavy static arp broadcaster client/server service, I realized that I could just make relayd a bit smarter in order to properly detect disconnected hosts faster (simply by double checking the arp table). I was also able to compile this software in an Ubuntu VM running in a VirtualBox on OSX for mips & armv7 (archer c7 tplink & wrt1900acs wifi extended setup):

./relayd -I wlan0 -I wlan1 -t 2 -p -1 -B -D -P
With a couple of arp table clean up helper scripts the setup is much simpler with this and less involved in managing the arp table entries!
