Wow, this seems ambitious. I only have a N810, so I fail to be your inspiration. But if you finish this, I believe that would allow for one of the more advanced (feature full) linux setups on a NIT yet. There are some ubuntu work being done, but that seems to be more along the hack and slash down to size route.

Do you imagine this is something you will see through? What are you planning to put on the N800?
