Indeed. sdlvideosink also has the 'xid' property, which does the same
thing... Then, you can create a window in the application and just send
the video-widget's XID to sdlvideosink and it'll do the evil hack for
you (makes you feel better ;-) ).

SDL always uses X, as far as I know... So that shouldn't be a problem.
You can make the window both on the application side as well as on the
plugin side... You could just make a gstvideowidget-lookalike and use
that XID (GDK_WINDOW_XWINDOWID(GdkWindow *window) or so), then you
wouldn't even have to change sdlvideosink...
