Can I share files over WiFi as a Windows share with my Nexus One? I have a Nexus One full of songs and when I go to my friend's house I would like to play songs off of it.  Since I have my phone connect to my friend's WiFi, the phone has a local IP.  If my phone's IP address is 192.168.1.101, I would like to be able to navigate to the phone via:

\192.168.1.101\Music

And have it open up a windows folder like any other share.  Then I could copy my songs, play songs off the share, etc.   Is something like this possible?  Is there an app I can buy?
