[Telepathy] Connecting a remote DBus Object over a DBus Tube

[tomw]

here we go:

using strace on the application gets me the following:

socket(PF_FILE, SOCK_STREAM, 0)         = 3
connect(3, {sa_family=AF_FILE, path=@"/tmp/dbus-REgYNwDrKY"}, 23) = 0
socket(PF_FILE, SOCK_STREAM, 0)         = 8
connect(8, {sa_family=AF_FILE, path="/tmp/dbus-gabble-eJmvd0ho"}, 27) =0

which I interpret as a connection to the remote dbus object under the
address "/tmp/dbus-REgYNwDrKY". However, I'm not quite sure what the @
in front of the path means.
btw, it's a 1-1 Dbus tube.


br, tomw
