I would say its gonna be a while. We are focusing on Amahi for Fedora 14 at the moment. The developer who was working the project has not been able to dedicate much time to it lately.
Hard to give an estimate, but I would venture to say not likely before the end of the year. Sorry I cannot offer more accurately, but I just don't know exactly what is left to be done or when progress will regain momentum.
We are a very small group of volunteers. Our current workload with Fedora 14 and keeping the existing Fedora 12 maintained is quite a workload. If you have some experience with Ubuntu development and would like to assist, that would be great.
