I want to download an Ubuntu ISO, preferably over bittorrent, and verify its integrity.

Currently, the following steps are required:

• start web browser, go to ubuntu.com, find download link
• find gpg signature for the checksums
• get the gpg key to check gpg signature of the checksums
• wait until download finished
• gpg verifiy
• checksum verification

Isn't there a simpler way? Just like

• apt-get install 12.04-64bit-ubuntu-iso
• apt-get install 12.04-32bit-server-iso
• etc.?

Of course, apt-get (or whatever it would be called) should download over bittorrent to remove load from the servers.

If it doesn't exist, it should probable post that at ubuntu brainstorm? Is there already such a tool? I wanted to ask before posting to brainstorm.
