Great stuff.
Is it possible to output to markup from these programs ?
It would be cool if python wsgi programs in this could work somehow.
Yeah of course! They've got STDIN/STDOUT/STDERR and I've built a Virtual Filesystem. But if you're using WASI binaries locally they don't have that restriction.
