I don't want to be a piranha and I understand that this is a community project, but the port to iphone seems to require quite a bit of time and effort in terms of code changes to adjust the controls.

I am considering porting it with accelerator support.

I will ofcourse release all the sources as required by the license but I also want to add several gaming servers to match players and act as intermediaries for players behind firewalls.
