Extent of synchronisation, possible loop

I'm up and running with WFF in a 4 node, Server 2008 cluster.
It's happily synchronising my content and IIS settings - so great job on the beta guys. Really painless setup.
When you refer to components being synchronised, do you just mean IIS components, or any server component or installed program? Where exactly are the limits on what is synchronised.
For example if I have the SNMP service installed and configured on the primary server, will WFF duplicate this installation and configuration?
Looking at the servers list, the system also seems to be constantly switching each node to 'Provision Applications', doing work, moving on to another node, then switching back.
I also seem to be seeing this appear repeatedly for each server in the log (been running for about 1.5 hours now).
Is it possible there's some kind of loop here?

I agree on the ease of setup...once I got past my firewall service issues (in another thread) every thing pretty much worked right out of the box.
As far as synchronization, I have been testing some things and I have noticed a few things. I created a site on the Primary server, and it was successfully replicated to the Secondary, however, when I added an IP to the site on Primary, that IP was replicated
to the same site on the Secondary. Then I changed the IP on the Secondary, and it was soon reverted back to the IP on the Primary. I can see replicating other binding information (like hostheaders or port/protocol assignments), but I can't see any reason why
the IP's would ever need to be replicated, I can't think of any scenario where this would work at all.
I also noticed that certificates were not in sync either. I installed a certificate into the cert store (not bound to any site) on the Primary, and it was not replicated to the Secondary until I created an HTTPS binding using that cert on the Primary server.
It would be nice to add the functionality (maybe as a Server or Server Farm Operation?) of syncing the cert stores between all machines without having to create a binding using them.
I am now going to test adding a completely vanilla Windows 2008 R2 machine as a secondary and see how/if the IIS install syncs. Will let you know.
