Well, as you've seen from the two responses already, the implicit answer to your question of "has anyone done any work" appears to be "no" :-). However, I think a number of us in the developer community see this as a fairly serious gap, and would like to remedy this. However, IBM hasn't been dropping S/390 machines and documentation in anyone's laps (at least, not mine, and no one else has mentioned it), so the primary facilitators would be, as with any new hardware port: 1) Access to necessary technical documentation and expertise 2) Access to hardware 3) Someone with appropriate expertise willing the guide ("own", if you will) the port to the platform through to completion, and continue to provide on-going maintainership in the face of adversity (someone adds fine-grained SMP support and it falls on the maintainer to figure out how that works on their platform, if no one has hardware). Part of the "real answer" is probably that IBM or a large consumer of S/390 machines has to shepherd the whole process to make it happen, and that probably involves a moderate amount of money, and moderate levels of frustration. If you can provide access to the first and survive the second, then you can certainly make this a reality. If not, well, it would be nice to see it happen but the task is to identify someone who can provide these.
