Syncing 2 iTunes Libraries (both Macs)

[applekid]

What's the best application or Terminal command to keep two iTunes libraries in sync?

I used to use PSyncX, but I'm beginning to find songs that didn't get transferred from my MacBook Pro to my iMac. I ran it again, but it forgot a few songs again.

I'm sure this topic has come up a few times, but searching wasn't working out too well.

This is a real pain for me. I have a PMG5 (which I'll refer to as the Master Computer), and then there is the MBP (slave 1), and a windows box (slave 2). I do most of my purchasing adding to the library on the master computer and keep track of the songs I add on paper. I then copy the files over to the slave computers and mostly in sync. If I add songs to either slave, i keep note of it.

If it gets really out of sync, I do a time consuming process where I copy the library from one computer to another and any extra songs will be copied and old duplicate songs kept in tact. Then I copy that back over to the first computer. I then unlink and relink the itunes libraries to the new folders and delete the old. (gigabit Ethernet is great here)

Podcasts are another ball of wax which I can never get quite right, so I mainly just do it on my MBP.
