This is currently not supported. However, adding this would be OK I
figure. This would require two changes however:

a) add NetworkNamespace= or so as a new service unit file setting that
   takes a a path to a namespace handle file.

b) teach .socket units namespace support, honouring JoinsNamespaceOf=
   as well as as supporting NetworkNamespace directly.

It's not trivial to add that, but patches would be welcome.
