Hi,
Current Enterprise Airwave server handles up to 4000 devices, since you have two AOS clusters with each 4000 APs , you can monitor each cluster with single Airwave server, for two clusters you need two Airwave servers and one backup for redundancy.

Q1 - Do MM's and the controllers send the same information in their AMON stream or does it vary.
ALL APs will termianted on MDs
Q2 - Should you be able to successfully configure airwave to work using the AMON stream from the MM directly.
Configuraiton need to be done from MM and apply it will automatically get pushed to MDs.
We can add Airwave as managmnet server from Configuration>System>More>AMON Receivers option and choose default-amp from drop down list and for ALE choose default-ale option.
in your case , each cluster will have only one Airwave/ALE entry.
Q3 - Should none of the above work, is there a workaround for the amount of AMON streams per cluster?
Could you elobrate more on this..
