So * still does the zap-sip conversion, but all sip peers register with
SER? Incoming Zap call goes back out to SER than peer, or SER handles a
re-invite to *?

Can SER equally distribute Zap calls among * boxes? Will it know if the
asterisk box is congested on the Zap cannels?

Have you implemented this before? (I would need some paid help)
