Kyanar: Still a couple of interesting ones in there - Office Live for example, I can't see many pirates paying Microsoft a monthly fee to pirate... Word documents?

Ditto for Skyfire, which is actually a web browser for use on iPhones and iPads to allow viewing Flash videos on legitimate sites like Youtube or DailyMotion.

I see Kazaa is on the list, despite being discontinued for close to ten years. Since Skype is technically and functionally very similar to Kazaa (being derived from the same codebase) has Skype been tested?

Scribd is used for sharing documents, mostly used from what I've seen for sharing court documents (transcripts, etc) and is frequently used by completely legitimate news sources (CNN, NZ Herald, etc).

Live Mesh Sync is actually part of Skydrive now, and can only be used to sync between your own computers - you can't use it to share with anyone.

If I see any more I'll let you know :)
