Well, I'll nose in here. You're right, the terms aren't so tidy. If you
was in the trade, you'd probly still call the LM1949 the "injector
driver" because it does all the smarts, and opt for refering to the
outboard current amp simply as the "external Darlington". Then
everyone's clear.

Don't worry about it too much. When language fails us, we can always
point and say "this thang here".
