Please, can this be added to portage?
I added an ebuild for a different TURN server implementation in bug #512254.
sorry if I'm a bit late to the party, but I recently added github.com/coturn/coturn to the portage tree!
Don't know if you're still interested and if it fits your needs?!
However, it would certainly be cool to have more than just one implementation, therefore I'm leaving these two bugs open for now...
