OK, so how does the id of the type object relate to meta_type as used 
in products?  Are those two meant to be matched/compared?

Also, am I correct in stating that getPortalType returns an immutable 
identification of the type, while Type/Title should be used only for 
display (human readable) purposes?

OK... can someone notate that in the source?

...and by chance, this is what CMFRating is doing.  OK, so I guess that 
means listContentTypes is depreciated too?  So what should one use, to 
get a list of types to compare to getPortalType()?
