Not by my definition of "production ready":

1. Not stable or up to date language spec.
2. Outstanding significant issues in the bug tracker.
3. No mature compiler.
4. No mature runtime.
5. No stable std library.
6. No entity/vendor that provides support/maintenance for a 
specific version of D for a specified period of time.

Would you use D for building software to ship with hardware 
appliances?

I would not.
