Got my N1 have Froyo, I want to stream my MP3's from my PC to my device.

Any idea on how I go about it?

Over Wifi (same network)

Over Wifi (2 different locations)

and if I'm really adventurous and if the network can handle it over EDGE.

Give tversity a try,

http://tversity.com

Or try Orb

Both work with pretty much all web supported devices. So your N1 should be fine (you can even stream movies if your connection is up to it!)

Already use tversity for on the fly transcodeing for my PC to 360. I'll look up their help and documentation and see if I can sort it.

Just as an aside a friend told me about a program, and I don't think it's Froyo or even android specific. (has an iPhone app too)

it's called SubSonic and it does just what i need.

I tried it out and it works great.
