Off topic, but what amuses me about the "Wrt" name is that it was originally alternate firmware for the Linksys WRT54G router from 25 years ago. The name has stuck for whatever reason; I guess since only geeks use it and know what it is.
Recycled 4 or so WRT54G variants a couple years ago I ran Tomato on for friend's small businesses and my home in early 2000's.
Similar to XBMC at least for a long time.
I'm pretty sure the software side of the project is a direct descendent from the WRT54G stack.
LinkSys got sued to release the firmware as it was GPL linked. This dump got modified to make the WRT54G way more powerful than LinkSys ever planned but they got to sell the hardware for years more than would have been expected at the time.
