I'm not sure I can install all the maps anyhow, since they're not mine, I would have to ask the author of every map before I could include it.
What I'll do instead is keep a updated list of where the maps are for easy DL - that way if you already have it, you don't waste your time, and you can pick and choose what you want to DL at your leisure.
I'm on 56k too - so I know the pain of unneeded DLs.
