actually it should work the way you've described it. I've tested it
right now by extending the hello example the same way, and the
capability was successfully transfered to the calling client as an argument.
By the way, why do you use Native_capability instead of Capability?
Although both should work, I would use the generic Capability class,
especially in an interface.

Best regards
Stefan
