And if you are stuck in h-pattern synchro mentality, or rpm matching mentality, and don't know what I am talking about, have a look at this starting at about 0:13 (sounds like straight cut gears except for top gear too, which is an interesting compromise). He has a h-pattern shifter here, which takes a bit more skill than sequential, but also doable, sequential would be easier to automate though.
EDIT: here is another vid from a manufacturer, talks about clutchless upshifts at 2:24
