I tried the software after seeing it listed on BitsduJour, pretty useful if you have more than one PC at home/work and want to easily share clipboard, URLs, files, etc. I no longer have to use a portable drive between machines or use email to share links or files.  It also works with Virtual Machines. A single license covers all machines in a cluster which I think is very generous from the author. :up:
