CMF doesn't currently make this easy; seems that it was not expected 
that types would be restricted on a per-user basis. However, types 
shouldn't show up if one doesn't have permission to create them. To this 
end, you can try to use the ZMI security settings to remove the ability 
of regular users to add Collector things, provided said things have 
their own permissions, which is not the case with all the default portal 
content and some external products.

You can extend these classes and provide your own security assertions, 
of course, and then make the types tool use your new class instead.

The real way is to give types a list of allowable roles (or security in 
some manner) and use this for the dropdown box and other machinery. But 
as we're getting into the CMF core, perhaps this is more a topic for 
zope-cmf at zope.org. Would be a good feature to have.
