Hello, I'm PowerPup. I just joined the forum. (Awesome forum by the way.) 
I almost succeed in a similar attempt, it ended up not working so well because I could not find a stable browser to work on my Mac Classic II. :lol:
What I had done was I used my PowerBook 3400 with IPNetRouter, this allowed me to route my DSL internet through the laptop's printer port and to my Mac Classic II.
I did some research and it seems your Farallon Etherwave has some sort of support for TCP/IP.
If your PowerBook G4 has Mac OS 9, you can use this guide to set it all up. Just make sure AppleTalk is set to Ethernet. And your Etherwave will do the rest. (I could even make a guide if it helps.)
---------------------------------
Okay, While writing this up I thought I'd also look for the drivers for your Etherwave, after some googling I ended up back to this forum! Link
If v2.3 doesn't seem to work you can try v2.2.2
If the drivers work out then you probably won't need any of the info I posted above. :lol:
Oh well, it was fun typing it.
Hope this helps.
