[sage-devel] How practical/useful would a native windows subset be?

It seems Sage really could do with a native windows port. I am wondering how practical it would be to make a version which is a subset of Sage, with something like Qt which runs on Windows, Linux, OSX and Solaris and has the look and feel of those platforms. It could make a Google Summer of Code

I think the whole closed source nature is likely to restrict the takeup of Sage for several broad groups of people when they realise that to get high performance they are going to need to store sensitive material on a Linux server they don't control. As a 50 year old engineer I have worked at thre

As I understand it, the SageMathCloud is closed source. Yet it is making extensive use of open-source code. Maybe the closed source bits don't link to the open-source bits, though I find it a bit hard to believe. If it did not link, it would not that be against the GPL? Or I guess if the code is no
