Or you could create an object on-the-fly that:
class TempPublishable(some base classes: Aquisition.Implicit maybe??):
    def __init__(self, the_string):
       self.the_string=the_string
def index_html(self, REQUEST=None):
          """return the string"""
          return self.the_string
I'm not sure exactly what base classes and security settings that
needs to be use on the TempPublishable?
Here is a real-life example of class created dynamically from SQL (cut
just to relevant fragments).

  from Acquisition import Implicit
  from AccessControl import ClassSecurityInfo
  from Globals import InitializeClass

  class theBasket(Implicit):
      """The basket"""

      id=meta_type = "Basket"
      title = "The basket"

      security = ClassSecurityInfo()
      security.declareObjectPublic()
      security.setDefaultAccess("allow")

      def __init__(self, id):
          ...

      ...

  InitializeClass(theBasket)

  class BasketGenerator(Something):
      """Basket Generator product kept in ZODB"""
      def __getitem__(self, id):
          """Return theBasket instance"""
          rv = theBasket(self, id)
          return rv.__of__(self)

Works just fine, including security declarations and acquisition.
