A powered dumper seems to be the way to go.

By similar arguments, a moving robot further than 1-2 feet away will, at the least, be a challenge to reach and dump into, particularly for long enough to dump all the stored orbit balls. I don't know the radius of the goal offhand. Isn't the radius about 1.5ft? If the error due to acceleration is just that, then the only real concern is the precision of a shooter. I can't comment on that

Also, 10 feet really isn't that close. Robots can easily get within 5 feet of eachother, I just envision trouble getting closer (and staying there)

There's no right answer, and teams will get both ways working, but I feel confident saying this just from the nature of this year's driving: if you can build a device that aims independently of your robot and propels the balls (at least slightly), you will have a much easier time getting balls in the goal. There are still other tradeoffs, of course.
