A 4th factor (kind of related to the others) is that the
chained CPU implementation generally means a greater delay
for Layer 3, meaning in practice more than a 1/2 second delay -
too much for doing a back-and-forth conversation, though
often fine for one-way transfers.
That's on equipment I had 5 years ago - what the typical
Layer 3 delay in equipment now, I'd have to measure.
