Number of concurrent storage replication tasks per host?

Does anyone know if it's possible to have more than a single VM replication task run from a given host system at one time?

Asking because in secure environments (ie using ssh for passing replication traffic) it can take a fair while for a given VMs storage to be replicated to other hosts. This is due to ssh being single threaded and not really taking advantage of the high bandwidth available on decent network connections. :(

So for HA environments using timed replication jobs to ship changes to other nodes (ie */1 schedule), it seems like the default serial nature of replication tasks is a problem. The storage replication ends up running behind the desired schedule because only 1 job can run at any time. (!)

If multiple replication jobs could run in parallel from each host, this wouldn't be a problem. I've looked through the UI, but not seen anything that seems relevant.

Does anyone have ideas?
