AFAIK, the only flash part is the uploader, and you can choose not to use it.
The board does indeed perform nicely now, still looking at improvements however . Keeping the crud outside does speed up the board by about a factor two at least I noticed. We have a scanner shell around the software now. Works like magic . Crud doesn't even get to the front door at the moment .
