I agree. And yes though that is inferrable from my anecdote, in fact I wasn't being pedantic. I actually probably used the terminology wrong myself, but all I really meant was, "what are your latency requirements in this system? How real time?" It was a conversational confusion because they kept using the term and I thought they were using it technically. When I realized they weren't, I didn't bother trying to correct them...

[edit] I'll add this conversation stuck out in my mind simply because I was a bit surprised that no one knew what I was talking about, that's all.
