Re: simple solution

"As it wouldn't distribute any MS code, surely it can't be illegal"

Under the DMCA, if Microsoft *says* it's illegal, then it *is* illegal. A takedown notice under the DMCA does not require the sender to *prove* anything - failure to comply with the takedown notice *automatically* subjects you to the scrutiny of US Federal law enforcement officials.

And, let's face it, under US law, if they want to find you guilty of doing something illegal, there are plenty of laws that make damn near everything illegal.
