I installed tversity on one of my unused workstations this weekend. I was interested in tversity because it can map network and external drives to the ps3 for streaming. it also encodes .flac for ps3 playback as PCM as the ps3 cannot read .flac.
You can even stream internet audio/video to the ps3.. I am using a program called uXM to stream XM radio.
All in all i am very impressed with the setup as i have all my music on my 500 GB WD external drive and didnt want to move it..
Anyone else gave tversity a try?
