it's spamware .... I entered a 'special' email address to download, and 'lo and behold .. I've gotten over 50 pieces of spam in that box in < 1 week ... and the inbox has now gone away. It's very doubtful that someone has randomly guessed the email address (24 random chars at a domain I rarely use). If you have a throwaway email acct I reccomend to use that for sure.

It is very windows centric, and doesn't have most of the features of transmit/cyberduck/fetch, etc. Not worth the spam to download.
