The service keys are also registered as service type, therefore it's possible 
to get a service by it's key. To make that work service types with prefix tx_ 
and user_ are disallowed.

Yes but it didn't helped :-)

I tried that but it didn't worked. Maybe I made a mistake somewhere. I have to 
check again.
Is it a bad idea to change makeInstance() into
function &makeInstance() anyways?

Would that still work with php5?
