By the way, I'm curious what features are missing from https://cloud.sagemath.com that you might need for it to work for your project? For example, what extra packages would you need, documentation, etc.? Too many bugs (if so, which ones, so I can fix them)? Is the network connection too slow? Not enough disk space? Compute servers are too slow? Last night I rolled out a feature so multiple people can collaborate on worksheets, files, terminals, etc. in the same project (=a Linux account on a VM) simultaneously, which could be useful for collaborative projects. Also, you can download and install your own copy of Sage into a project on cloud.sagemath, and even switch to using that copy of Sage for worksheets.
