depends on the GPL, they added a piece for Tivo recently. I am no expert, but I remember the part about Tivo and their code not being GPL, and there was something added to prevent that, which is where this would fall I would think.
You could also setup a DNS server on one of your machines if you are trying to access it from the others, but that is time consuming and would be overkill if you are trying to just get that one computer working.
this may not solve it for what you want to do, but just add that address to your hosts file
127.0.0.1 rick.redirectme.com
that will get you back to your computer with the name and also others to it from the outside
