Check this out...

You ask for Longhorn kernel patches, there are here (Credits go to Knabe91, for this thread).

However I wouldn't make private release, or publish this because of eventually C&D from Microsoft.

So its status is unreleased/unpublished.

However I want to see what you think, about my idea?

I think it's an alright idea.

I think its an excellent idea and you should publish it somewhere

I think it's an incredible idea.

Good idea

Awesome idea

I've release that, Longhorn or LH are not TM - TradeMarks which I've used in name, so I think wouldn't be a problem with Microsoft.
Other think MSI files are edited with ORCA (Microsoft's product) what also is not illegal
Hounsell produce winlogon cracks and he has not any problem with that, and I've produce kernel patches on Knabe's method, so I think the whole disk wouldn't be a problem, but again I'm not sure.

Maybe if you not sure, why not use PM instead 8)

Looks pretty useful nice idea!
