Lol.
Probably not considering how long Ephi has worked on it.
Considering what RTB is, I don't think it'd be particularly hard for a group of people to spend a few months making something competitive. This isn't a matured company, its just a mod that isn't really THAT stunning.
RTB gives players a convenient messaging system, some extra management tools, and a server to host mods on with a front-end to download them in-game.
Don't get me wrong, making something like RTB won't happen over night and Ephi did a good job. But in concept its not that impressive.
