This is a cool idea, but it may not work because FDS uses the
AD sync control to perform incremental inbound updates.
It's quite likely that the two AD servers would have different
states for the sync cookie. You could work around this
by initiating a full sync when failing over between ADs.

THanks for the comments so far, it appears that if I can mitigate the risk, then I can just leave a single agreement in place between FDS and AD.

The other question though, regarding one-way from AD to FDS - anyone got any thoughts on that?
