David,- I believe what you are asking for could be implemented quite simply via
CruiseControl's <buildstatus> modifications with some Ivy help, perhaps, but
without extra complications or the Cruise Ivy plug-in.

1. Create Cruise projects for your branches (F v1, F v2, C v1, C v2)
2. In your Cruise builds - publish project artifacts upon success into a local common
Ivy repository. Use Ivy's branch attribute or other means to distinguish
integration builds from releases.
3. Make F (Ivy-enabled) build consume appropriate (latest) B, C, D integration builds.
4. In CruiseControl config - use <buildstatus logdir="a log directory for C branch project"/>,
etc. in F's <modificationset>

As a result, after Cruise builds, say, a C branch successfully, a consuming F branch build would
kick off.
