We don't use Ivy, but we do have our own set of extensions that has some similar concepts in terms of multiple projects with dependencies between them.

We use multithreaded build dispatching based on a dependency graph & let me tell you: it's not an easy thing to get right. I've had to make several changes to core Ant classes to get this stuff working properly.

Of particular concern is logging: your logger must be able to deal with the fact that you have projects running in parallel or your logs will be an incomprehensible jumble.

Not trying to discourage anyone from giving this a go, but it's certainly not for the faint hearted.
