if I'm not mistaken, this time they could have been smart to release to public this development tool in order to avoid modding.
I mean, if you have the ability to run homebrew without having to care about soft or hardmod, relating to alternative dashboards, emulators, divx players, internet radio streamers, and so on...this should be a great move for both (them and us).
the focus is of course gaming development, but if this tool can do more, they just gave natively a bridge to accomplish much without going to breach the 360.
if instead is too closely focused on just that (gaming), they just keep the approach to invite modders to get more on the console like has been done with xmbc on xbox for example, having the benefit of a modded xbox with ftp support.
