Thanks. Yes, I think this is what the original comment meant that I was asking about. Now I remember where I read the term "spec work" - it was some weeks ago on avc.com, Fred Wilson's blog. And someone gave the same answer there as you, IIRC.

It's not specifically a tech term, e.g. spec scripts in the entertainment business:
