Seconding this right here.  At what point is the line drawn between "accelerator" and "essentially a new computer shoehorned into a classic Mac"?  Right now the only thing this doesn't have (potentially) that a new computer would is a sound card.  Don't get me wrong, I like the idea of an affordable accelerator for a system where current options are near unobtanium (either by scarcity, cost, or some combination of the two) but I think the feature list should be pared down somewhat.  An upgraded processor, RAM, and upgrading the internal video from black and white to grayscale is a good stopping point IMHO.  Replacement storage and the addition of external video, WiFi, USB seem a bit excessive, unless they are left as potential future features to be implemented using an expansion card.
