I don't know when I'd do it in relation to finishing the other project, but it's sort of immaterial since I don't have the authorization or code I need to proceed at this time, and I don't know when, if ever, that situation will change. I don't know if I will need additional programmers, but I don't think so. One of the other people working on Ostendi is the programmer you know here as ferazel_09, so I'm sure he'd be willing to provide assistance on a Cythera port if I needed it. If it goes the open-source route, the more the merrier.
With Xsera all it took was RedSteven to convine Nathan Lamont to give out some code and programmers joined together.
We'll see how things go. I'm cautiously optimistic.
