Wow. This sounds really helpful. Would've been nice back when I ran a server. I hated having to use a whitelist, but a lot of the time they are a necessity for smaller servers without huge moderation teams.
Your client is contacting http://session.minecraft.net/gamejoinserver.jsp. There should be a "/" between "game" and "joinserver.jsp." Not too sure what might cause that. I'd recommend trying to force an update of the client and seeing if that fixes the issue. You can find it under "Options" on the launcher.
If you use Bukkit to host your server, you can use the Hunger Games Network plugin, which can be found here. It's made for 1.3.2 though, so it may or may not work. I've used some pretty old plugins on my server before.
PlanetMinecraft has got a lot of custom maps hosted on it. Stuff you download from there is usually safe. Most stuff here is too. If you aren't sure, you can always try scanning the files with an antivirus.
This probably isn't the proper place for a thread like this. Modded Client Support is for getting help with modded client problems, not maps. Try putting it in the "Maps Discussion" subforum.
You have to send the data to a certain script on their servers. Just entering http://www.minecraft.net won't work. I just didn't know if they still have it as the new registration system won't let you get a username until you buy the game.
I'm working on a project that contacts http://www.minecraft.net/haspaid.jsp to see if a user that is authenticating with Mojang's servers is a premium user (to discourage piracy), but have been getting reports of a 404 error. After investigating, I found that it is this check causing it.
Was this link moved somewhere else? I know Mojang's been changing their backend a lot to encourage use of the Mojang account system.
You can change them in-game with cheats enabled. To enable cheats, you need to create a new world with them enabled or use NBTEdit. To use NBTEdit, run it and open the level.dat file in your world's folder (it can be found in %appdata%\.minecraft\saves). From there, under "root" and "Data", make a new Byte (the grey dot) and name it "allowCommands" (case-sensitive). Then just double click the Byte, setting the value to 1. Close Minecraft, save in NBTEdit, and restart. Your world should now have cheats enabled.
I'm sorry to say this, but that's impossible. Windows RT apps are Silverlight-based, so launching Minecraft would require calling javaw.exe to execute Minecraft's code. The problem is that since Windows RT apps are sandboxed, they can't access anything outside of their own resources. In other words, with the current setup there is no way Mojang or anyone will be capable of creating a launcher for Windows 8.

Agreed. Also, with BUDs broken it's going to be a lot harder to make custom maps.

Yeah, I got the RTM of Windows 8 and the Metro apps suck. I'm fine with sticking to my desktop apps, Microsoft.

They will still attack you, but will not damage anything in your world.
