The Skcraft Launcher combined with the massive amounts of new possibilities of Alice unmatched by other servers, the ease of use extraordinary, but have you ever though of providing a downloadable server package compatible with the Alice Client so that we don't have to manually update the server mods, and plugins to work with it? Just an idea, maybe you guys have already thought of it but have come across issues with security or something along those lines, but just putting the idea out.
I'm not sure if I got what you were asking for, but I'll cover two bases of what I think you were asking. Please correct me if I am wrong! Can the launcher download other packs like Alice? Yes, but they must be signed by either Mojang or sk89q for security. This can be changed by modifying the source code to allow other certificates. (discussed here) Can you release the Alice server files? No, Alice is a finely tuned piece of software that is unique to this community.
