Depending on the game and size and how good a connection you have
no use of doing this its better to mode the xbox 360 and download games in your hardisk it will take around 7GB
It depends if your xbox is fast or slow!

It really depends on your internet speed.
If a game is out of date, the Xbox will prompt you to download the latest update for it. Updates are usually around 4MB and do not take long to download.
It will take several hours as the game will be many many GB.
Um... You don't download Xbox Live dude... It's an online service. You can download things from it however, like videos, demos, full games etc... Elaborate on what you mean.
It honestly depends on the memory that your Xbox has and your internet connection. 6.86gb will download faster on an Xbox that has 250gb and great internet connection, than an Xbox with 20gb and poor internet connection.
People come up with ideas for video games, they programme them, put in graphics, get a licence for xbox, and then sell it. However, this does take a long time.
Depend on your internet. If your internet is crap, then it's longer.
