:-) Same old problem.

directly using the raw API.

Can you develop that a little bit? Are there any known bottlenecks in the
code, or are you simply after a less cpu intensive solution?

that we would only have to maintain 2 APIs in the far future. But that's
not going to happen soon, I guess.

And the reason being the performance issues you mention above?

I have already turned right a few times now, certainly spent a lot of
money and effort 'over there', and I therefore hope that turning left is a
better long term solution for me, but that obviously depends on how high
the mountain is to climb.
