Comment 4 for bug 1161441

@Dan Smith (danms) :
yes, it can create a network with project_id,
but it cannot associate a non-associated network to other project except the admin own project.
please look up the reference in api.openstack.org/api-ref.html
or looking into the source code of netwroks extension.
it does not provide a way to accept a project id as parameter, just extract from context.project_id
