context.REQUEST ?

Folder, hmm
http://www.zope.org/Documentation/ZopeBook/AppendixB.stx
class Folder
(also look at <zoperoot>/lib/python/OFS/Folder.py)
but you can't do anything except adding a folder.
however, the code for folder shows it is (among others)
derived from OjectManager. AppendixB class ObjectManager
(and the sourcecode also) contains a lot of useful methods
like objectItems( [list of] string ) where the string denotes the
wanted meta_type, like so (from the top of my head)
objectItems( ['DTMLDocument'] )
this gets you a list of tuples (id, obj) of DTML Documents contained in the folder.

never bothered abt CMF. however, REQUEST most probably contains
AUTHENTICATED_USER (if cookie-based auth)
