Comment on Network Beacon

just started using yesterday to share my home itunes library as if it was on my current network. found out about it (and was able to set up) by following this site:

i'm still fairly new at SSH, but i was able to get this going within minutes.
I'm truly surprised this is not used by more ppl!
