Nope. The idea is that 

      foo:bar:baz:waldo

is kind of "path": connect to host "foo", enter its container "bar",
and from there connect to "bar"'s container "baz" and then further
down into "baz"'s container "waldo"... Containers are stackable after
all.

(Not saying that's actually stacking containers is a great idea, but I
think the basic concepts should cater for that. Also, currently nspawn
can be stacked as a matter of fact...)
