I mentioned this to Ashley before, I think. Game Jolt offers an API for retrieving nearly every bit of information on the site. We'd be willing to host all the files, screenshots, soundtracks, information, etc. and the Construct site could just pull all the information in through the API and display it on their site. I'd even be willing to help code out the section on the Scirra site.
We even have plans for implementing a bug tracker, project forums/chatrooms, SVN/Git repositories, project Web space, etc.
