It does not look like the pins are 5v tolerant.
Given that there are a lot fewer pins on the 1281 than on the 1280, I'm wondering if there will be enough to push out to the arduino pins... we'll have to check to see if all CPU pins are exposed or if some are used within the module.
Inopia - when you say "arduino mega based sensor nodes" do you mean every node has an Arduino Mega attached?. Or that each uses a mega mcu?.

I've created a shield board that will be available sometime in November 2009. It is a video overlay board that uses the MAX7456 chip from Maxim. I've not determined pricing yet, but once I have I'll add it here and update my site.
Personally I'm interested in developing my own routing protocols so not a big issue for me.
