Yes, these are very cool features and it's good to be aware of hack-nix
and thank you for pointing it out.  It's just not perfect for me right
now, since for a system that is about distributing development
environment to multiple computers, compiling everywhere from scratch is
not good enough.

But I'm sure that I'll find places where hack-nix is perfect and I will
try to remember to use them there instead of reinventing something worse.

Thanks again,
