Can all XBLA and DLC can be put to non jtag xbox?

I saw a thread in other forum titled "XBOX360 XBLA and DLC - Non JTAG""

Now my question is, can be all DLC can be injected like lips song?

No most of it is tagged to your 360 hardware/gamer ID

The only reason this "non - JTAG" stuff works is because it's bundled with a profile that BOUGHT the stuff legally.

It'd be very easy for MS to start banning all consoles associated with the gamertags that have been shared around with some DLC...
