With the news yesterday about logmein & Hamachi, I was exposed to my first knowledge of the product. I've used logmein products for a while now and this is really the first I've heard of Hamachi, though with A) the track record of me and logmein getting along and B) their description of what hamachi is and what it does, I'm starting to really look into it.

Does anyone here use Hamachi? If so, for what purpose and to what end? How satisfied have you been? Any information would be greatly appreciated.
