Continuations are used to transparently migrate the program's execution to another computer so that a computer program can always act on local data, even though the data is distributed across multiple computers. I don't think this can be achieved without continuations or something equivalent to them.
It has, unfortunately, been rather dormant for the past 6 or 7 months, despite my best efforts to jump-start it. The issue is probably a combination of it being extremely ambitious, and me not taking things far enough that it becomes self-sustaining.
People have periodically expressed strong interest in contributing, but this has not yet translated into an active self-sustaining development effort.
Unfortunately, other commitments (ie. my day job) limit time time I'm able to spend on it, but I will do what I can to support anyone who wishes to contribute.
