After a great in depth convo with @ryanhiebert, it seems we may need to drum up some examples to compare and contrast how tractor is a lower level system in comparison to celery / amqp and can be used to build such load balancer patterns. A more general actor model system like tractor or a scalability protocols system like zeromq considers such patterns special cases. Emphasis on SC in these examples should be paramount.

I'd also like to glean everything from those communities that can be used at the "tractor level". I've already noted a few things:

• the celery remote debugger, something I've already mentioned in the docs
• the supposed improvements to multiprocessing.pool that were added in billiard
• tasktiger seems interesting as a celery competitor

I'd like to use this issue to track the discourse surrounding how tractor can support the needs of (ex) celery users who are looking for a SC alternative.
