We´re working in a project
: "Electronic Rapid Prototype Hardware".
The main idea is to have an ECU to be able to be very quick in a prototype phase of a project.
At the moment we´re working joining a linksys router (or similar) + Arduino Mega + specific hardware to have rs485,can bus,...
We try work as easy as possible (DD-WRT, shell script,...). For sure, there are better methods (openwrt, cross-compiler,...), but it requires high skills.

You can find all the information about Linkduino in
. Sorry, it´s in spanish (maybe google traductor can help)

Igor, this is awesome!
I made a similar setup using a Fonera (Fon2100) router running OpenWRT that talks serial to the Arduino. It works just fine connected directly.
I just wish there were some very small and cheap routers for all this that could be standardized on or sold as some bare-bones kits.

Thank-u!! I´m doing the same as you (not directly because is 3v3). At the moment, I´m triying only with DD-WRT, in stead of OpenWRT, because it has an easy configuration web page.
I also try to do the router programmation using bash scripting.
The idea is to have a "generic hardware" for the prototype phase of an electronic project (always trying the easy way to resolve things).
What have you done with arduino+Fon?

The Arduino (or ATMega168 chip) seems to accept 3.3v TTL serial signals just fine and the FON router I'm using reads Arduino's 5v signals just fine too. I haven't noticed any problems using both directly but it's probably better to have a proper converter like in your circuit.
I'm using OpenWRT and the ATMega168 with Arduino firmware to monitor and control a hydroponics setup for growing plants. My code is here:
I initially tried to use DD-WRT but found OpenWRT to be much easier to use and modify, plus very lightweight. Their LuCi web-admin pages are powered by a Lua-based MVC framework that I found very easy to extend. Plus Lua is very lightweight and I use it as a 'daemon' script to send and receive over serial from the Arduino. I have some pictures of it here too:
The software is pretty hackish and very specific to my needs though. Something more generic like Firmata would be more appropriate for a general prototyping solution.
