If the Analog Buffer is inside the DLL, then the analog return loss of the
buffer is not correctly handled in the impulse response of the channel.

Why not? As long as the dll is isolated from the analog front end , the
dll itself can be modeled any way you want

What nasty things are likely to happen if someone puts the analog buffer
model inside the DLL?  At the very least, the impulse response will be
incorrect.

Are there any circumstances under which this can work correctly?
