The way I read it is if your LAN setup wasn't working with the Roku getting a DHCP IP address before, and your wife had to set your Roku to use Static IP, when you upgrade to .35 your wife would have to do that again. Now, if your Roku isn't for some reason able to get a DHCP IP, I'm not sure how you would telnet in to set it up for static? I'm using static myself only because I wanted to, DHCP worked but I wanted it static for various esoteric reasons.
If you don't have a DHCP server then its definitely trickier to setup a static IP address, I can think of two ways though:
1) Talk to the Roku via a serial cable
2) Write a small shell script (hardcoded with the values you want to set your static IP address to), put it on a compact flash card, and call it from the desktop.
I wouldn't consider either of these as being 'trivial' (though I could help with the 2nd solution).
If you do have a DHCP server then its certainly easier, you'd get an address, telnet in and then vi (edit) the necessary file. I wrote a shell script that makes that process easier though (no need to use vi).
