Yes, you should be able to use the XTest X extension to inject keyboard 
or mouse events, with:

XTestFakeKeyEvent(dpy, keycode, is_press, delay)
XTestFakeMotionEvent(dpy, screen, x, y, delay)
XTestFakeButtonEvent(dpy, button, is_press, delay)

How to handle accessibilty with Hippo widgets is still being discussed
-- we won't get dogtail/at-spi support automatically unless Hippo uses
standard GTK widgets, which probably isn't going to happen.  Maybe we
could write a layer to teach at-spi about Hippo..
