Sharing library from 10.3.9 with 10.2.8

Question

I have two computers on a home network:
1) Mac G4, running 10.3.9, directly connected to the Linksys router, model WRT54G.
2) iMac G3, running 10.2.8, wirelessly connected in another room with a Linksys ethernet bridge (WET11).
I would like the iMac to access the G4 library because that is where all my music is stored. (no music is on the iMac right now).
Both computers use iTunes 6: In preferences->sharing->I have checked "look for shared music" and "share my music". Under the source list on the G4, I can see and play the iMac Library great. However, the iMac is not showing the G4's Library.
I went into the G4 System Preferences->Sharing->Firewall and made sure that the "iTunes Music Sharing (3689)" port was enabled. On the iMac, that port wasn't listed... so I tried clicking "New" and specified the 3689 port. Restarted both computers, re-launched iTunes. No change. Funny because ordinary file sharing and internet access works fine on both computers... it's just the iMac cannot share the G4's iTunes library.
Any ideas would be appreciated. Thanks

Answer 1

To anyone who might read my original message: I found a way to make it work.
On the G4, I created an alias for every album folder in my iTunes Music folder. Then, I went to Finder->Go->Connect to Server->, and connected to my iMac. Next I transferred all those newly created alias folders to a new folder on the iMac's desktop.
Then, on the iMac I opened the iTunes application, went to File->Add to Library, and found the alias folders on the desktop. Pressed "choose" and after a little time they were all added to my iTunes library on the iMac.
Works great as long as I have the G4 volume icon connected on the iMac desktop.
