Hi,

	Sorry, clarification: I know how to pass FDs over a socket. I want to try passing FDs over D-Bus. What I am looking for is something that a typical Ubuntu install provides “out of the box” that will send and/or receive a unix FD over D-Bus.

	Does that help?

	I suppose I could rig my own two endpoints to pass messages w/ FDs back and forth, but I’m just trying to save myself that effort.

	Thank you!
