Stay away from freeWire .
Of all the LimeWire forks it's the worst yet .
They do install spyware .

- Buy LimeWire Pro for $ 9.50
- Compile your own LimeWire using the source
- Download and use Clean LimeWire
- Download LimeWireNOVM.zip from www.limewire.com and alter ads.props

That are about all the options .

Also , you can't set up a private transfer .
Gnutella is a public network .
Even if you do set-up a connection up between to clients , if you make a mistake somewhere in the config and your ( or his) client makes or receives an other connection your file is shared for everyone on the network .

If you need to make private files availbe tranfer set-up an password-protected FTP server or HTTPS web server .
