I love PDAnet for android, works great on my Windows machine. Unfortunately, I just found out (after installing Ubuntuon my HP mini) that there's no Linux client. Can anyone recommend a tethering app, non-root, with a Linux/Ubuntu client?
Try AziLink (http://code.google.com/p/azilink/). You will need to do a little setup on your Ubuntu machine in addition to loading the app on your DROID, but it will work without requiring you to root your DROID. This is a USB tethering solution that I have used in the past with my Ubuntu netbook to great success.
I used this modified version of Proxoid for quite a while.
You need to set up the android developer kit first, and follow the instructions on the Proxoid website on how to enable it.

Easy Tether from Mobile Stream should work. It's a way to share your internet connection with another device via USB. Get the Lite version (does not support https, or tethering to gaming consoles) or the Full version.
Supports Windows 7/Vista/XP (32-bit and 64-bit), Mac OS X 10.7/10.6/10.5/10.4, Ubuntu 10.4+ and Fedora 13+
Full version supports the following:
Tether PS3, Wii, XBox via PC Internet Connection Sharing, you need a computer for game console tethering.
