I haven't tried this, but I have installed Ubuntu Netbook Remix to an ASUS EEE without a hitch from a USB stick. Is there a particular reason you need to install from CD/DVD? The netbook I installed it on didn't have an optical drive, USB of one form or another was the only option, and it was simple.
