I am not sure what connection there could be. Does Frostwire do something novel or revolutionary that makes you suspect?
Just wondering.
Well it looks like an ordinary Bittorrent client*, so I doubt Satoshi would be involved in this. Remember Bittorrent was created by Bram Cohen in 2001, by the time Bitcoin was released in 2009 Bittorrent was mature and mostly complete and it seems Frostwire is not pushing any particular tech to the edge.
*(Unless I am missing something about Frostwire, it just seems like an ordinary Bittorrent application)
:p
