Gareth,
I did have it working (well within the limits of the software at the time). As for steps, I don't recall off the top of my head. I can dig through my notes this weekend (I'm at work & notes are at home) & I will post some steps for you to try.
A quick note as to what was not working in the version I was using (0.2.0) - the interface for restarting mt-dappd was broken (I think this was a known bug for the project).
The impact of this:
Say you had an i-bay setup to dump your music to, then you start mt-daapd. mt-daapd would index the ibay & serve this up to your iTunes (worked with Win & Mac) fine. However, if you added more music, the only way I could get mt-daapd to index & recognize the new songs was to actually restart the box. I guess this wasn't too bad if you don't add fequently. I had to put this side project on hold while I dealt with more pressing issues, so I never really checked to see if there was a way to (easily) correct this.
Anyway, I'll post the steps as soon as I can.
Please check back here this weekend (read late Saturday).
Also, it looks like the project has posted a newer (unstable) version to try, so I might give that a go if I have time.
