Two things that need fixing :
1. support for class constants for internal classes. Christiano has
already posted a patch.
2. session support for internal classes. should we have a Serializable
interface which classes inherit, or have sleep and wakeup
handlers in the zend_object_handlers structure ?

I applied his patch. As I told him I don't think persistent internal
classes across requests will be supported with all the bells and whistles.
In general they should work but I expect more problems to be found such as
not being able to initialize constants with arrays (which is no big deal IMO).

I guess it's possible. In most cases I think internal classes won't be
serialized though, such as COM. I don't think it needs fixing though. It's
something which can be added whenever...

Actually, people have already tried to serialize PHP5 COM objects
and hit a segfault :-)

It should be reasonably simple to serialize COM objects (there are
a bunch of IPersistXXX interfaces we could use); the limitation right
now is that our internals don't provide a sane way to implement it.

I can probably whip up a serialization interface over the weekend;
it would work a bit like the iterators stuff - driven by a C interface
that could wrap a userspace implementation if desired (although I'd
be more interested in the internals here).

Sounds fine to me.
