Alright, so despite one setback of minor idiocy, here is the truly working
code.  HOWEVER, I believe that it should probably contain some more general
information, as in setting the element details, etc ... Also need to add in an
example of setting caps, etc ...

How's it look?

-------------------------------------------------------------------------------
import pygst
#pygst.require('0.10')
import gst
import gobject

class TestFilter(gst.Element):

  _srcpadtemplate = gst.PadTemplate ("srcpadtemplate",
                                     gst.PAD_SRC,
                                     gst.PAD_ALWAYS,
                                     gst.caps_new_any())

  _sinkpadtemplate = gst.PadTemplate ("sinkpadtemplate",
                                      gst.PAD_SINK,
                                      gst.PAD_ALWAYS,
                                      gst.caps_new_any())



  def __init__(self, name):
    gst.Element.__init__(self)
    self.set_name(name)
    self.srcpad = gst.Pad(self._srcpadtemplate, "src")
    self.sinkpad = gst.Pad(self._sinkpadtemplate, "sink")
    self.add_pad(self.srcpad)
    self.add_pad(self.sinkpad)

    self.sinkpad.set_chain_function(self.chainfunc)
    self.sinkpad.set_event_function(self.eventfunc)

  def chainfunc(self, pad, buffer):
    return self.srcpad.push(buffer)

  def eventfunc(self, pad, event):
    return self.srcpad.push_event(event)

gobject.type_register(TestFilter)
