sure it might be a neat little hack - __call() can be used for alsorts
of wonderful madness but do note it can become a maintainance and/or
documentation nightmare ... not to mention that it doesn't work with code
completion in any editor I know.
and having read what you wrote about Propel/Symphony I still don't
get what the problem is that your trying to solve ... although I suspect
that your probably suffering from a lack of late static binding
(which, if we had it, could be used to minimize alot of repetitive boiler
plate code in [for instance] 'data object' classes that extend a common
base ... then again I may be wrong :-)

the 'callback' type has a number of forms:
'myFunc'
array('className', 'myMeth')
array(self, 'myMeth')
array(parent, 'myMeth')
array($object, 'myMeth')
self and parent adhere to the same 'context' rules when used in call_user_func*()
as when you use them directly - whether $this is present within the scope of the
called method is essentially down to whether the method being called is defined as
static or not. AFAIK call_user_func*() respects PPP modifiers and works transparently
with regard to access to the relevant object variable ($this)
