If you add the async annotation to the method in the XML file:

<annotation name="org.freedesktop.DBus.GLib.Async" value=""/>

Then the prototype of the method changes to pass a
DBusGMethodInvocation* instead of a GError* (and there are no out
arguments).  You can then do:

char *sender;
sender = dbus_g_method_get_sender (context);

Easy!

Just because you mark the method as async doesn't mean that you have to
return in some other context, at the end where you would normally set
the out pointers and return TRUE simply call:

dbus_g_method_return (context, out_arg1, out_arg2, ...;

For an example see
http://svn.o-hand.com/view/eds-dbus/trunk/addressbook/libedata-book-dbus/, specifically e-data-book.xml::getBookView() and e-data-book-c:impl_Addressbook_Book_getBookView().
