I'm hoping we're be able to port libuv to IncludeOS (which should be doable, much like libuv IncludeOS is eventdriven). Then we should be able to get Node up and running. Running Node.js through IncludeOS on Nabla could be interesting in a "FaaS" context.

Last I heard the author of Rumprun has picked up beer brewing full time and isn't interested in maintaining the project.

It would be great if someone where to pick it up.

OSv is also very relevant. They provide a much richer and more compatible runtime environment compared to IncludeOS (I think they even have zfs). And OSv is pretty active these days, so if you looking for a way to run some high performance stuff OSv is worth looking into.
