as an ECF adopter, please add your project to the list of adopters . :-)

AFAIK none of the current providers support NAT traversal. But the
implementation  of the OSGi Remote Admin specification that is
currently being worked on, could be used to integrate e.g. STUN  to
advertise the public IP address on the service provider side. UPNP 
might be a candidate to set up port forwarding.

 is also worth the read, but might be slightly outdated.
