Might look into hosting my own server if it's simple, because I can keep my computer on longer, so when Boosted is off we could have a second world to play with.
EDIT: Only issue is I can't do the port forwarding, is there an easy way around that? My router needs a password which I don't have.
There's no way around that other than completely bypassing it by connecting straight to the modem if you have a separate modem. But if you don't have the password and someone else isn't trying to keep you out of the router, you can easily look up the default password for your router on Google and try that.

Free subdomains there, and if you have a router, dd-wrt or other software is able to autoupdate your IP for that domain every time it changes
It's only minecraft.jar, I think that's enough. Just do what you'd do with any other texture pack, it's already been patched for 128 textures Problem is, I have a few other mods, and it might not like it that you don't have those But try it.
The whole minecraft folder was 30 mb zipped, don't have time to upload that right now
I did a quick test not long ago experimenting with higher res textures, but Minecraft would crash on me when I tried that. Guess he's fixed that issue.
Actually, I don't think Notch has done anything about it.
You need to run this patcher, and choose the texture size. The game will be changed, so it backs up minecraft.jar automatically. You might want to keep a completely standard copy to begin with, because we'll be installing several mods to make it like mine.
