I found out Axis is based on quite old bitcoin source. To update all the libraries and all bitcoin source changes is possible, but also quite a job.
Another approach would be to take the latest bitcoin source and implement the Axis blockchain into there. This will take a bit more time, but Axiscoin will get lots of bugfixes and new features for free.
I feel a bit more for the second approach myself. Any opinions?
(by the way I have no plans at all for forking the blockchain yet)
