 That'd sound ok to me.

+My first thought was to use ((void *)1) and ((void *)2) for ANY and
+NONE, but that causes problems testing for NULL.  I don't know why
+anyone would need to test for NULL, though.
+
+GST_CAPS_NONE probably should be NULL.  It can be used as the end of
+chain indicator as well.
+
+I like the idea of making GST_CAPS_ANY a fixed number, since that
+makes it easy to test, instead of needing a GST_CAPS_IS_ANY(). 
+Alternatively, we could special-case gst_caps_copy() so that it won't
+actually copy the ANY caps.
