Would it be within the realm of possibility for Open Sauce/Synapse to enable server-client map downloading? I'm pretty sure it's not since OS is mainly for map creation, but it would be awesome if it could.

I'm referring to trying to solve the horrible way that CE hosts custom maps, if a client try's to join a server without the custom map they're denied. If Open Sauce could somehow let the client download the map from the server (or another external download location) I'm sure custom maps would become more popular! This would have to be a server-side application obviously.
