You would need to ask them. Whether they (any other site, not just Curse) choose to support this way of making one application work for everywhere, or not, is entirely up to them. We will certainly be willing to help them write a module to plug in to it if they wish, and we will be more than happy to host any official modules that are made for other sites, but we won't be writing them ourselves (unless they specifically and officially ask us to), for very obvious reasons.
