Currently GNU Parallel will only print out all the output from a
single server. Some might consider that good and others might consider
that bad. It will, however, require quite some work to make it mix the
output from different servers but still have the output grouped (so
they do not mix in the middle of a line).

Give it a spin. If there are no problems I will make an alpha release.
