You can avoid entering spaces by lifting your finger when it isn't touching the centre area. It disrupts the flow significantly when you do so but it does let you stop half way through a word without putting in an extra space.

After playing with it for a while I think that it's an interesting idea. I'll stick with it until I'm familiar enough to make a fair judgement but it's difficult to imagine 8pen being as fast as the standard keyboard - there's just too much movement involved for every character.
