The dash is pretty easy to setup, if you read the .properties file it has all the co-ordenants for the objects, it's not very hard, just lots of trial and error to get it all the line up. I'll send you all my files when i've finished it, the only footage i've got is the demo footage, I havn't got a cam yet.
The eeepc is a laptop with a solidstate hdd (8gb SD to be exact). For Targa (where the nav can start it logging, and slam it in the glovebox ), and super sprints I think the eeepc will do me fine. But for proper circuit racing I recon it'd be a pain.
