I wish someone would teach all these projects that you need to 
describe what you're actually doing up front. AFAICT just from 
their other website at https://cloudabi.org, whose front page 
isn't much better than the one you gave, that would be "A new 
capability-based C runtime and APIs so that all your cloud 
applications can be secured and run portably across any OS we 
support." What's their solution for multi-arch, separate or fat 
binaries?

Capabilities are nice, but I don't know enough about security 
tech to say if they're much better than other sandboxing tech. I 
suspect that security is still a hard sell for most, and it will 
not go farther than those few niches who care.

Of course, as all it seems to need is libc support, some API 
wrappers in D, and maybe some ABI tweaks, which is no different 
than porting D to any other common platform.
