Communication between hosts

Hi everyone

Henrique here from The Machine Must Work.
We make CEP panels and started recently to dig into
how our current panels would migrate to UXP.

One topic that I could not find anything about is the communication between hosts.
We have a CEP called Thumbs Up which runs
in AE, PR and PS.
For this one to work the panels in each host need to talk to each other,
and be able to launch other hosts if not already running.

Is there anything already available or planed in UXP that will act as Vulcan does in CEP?
Something to launch other hosts and send messages between them?

Many thanks!
