I am using F13:
yum-3.2.28-4.fc13.noarch
gnome-packagekit-2.30.3-1.fc13.x86_64
PackageKit-gtk-module-0.6.6-2.fc13.i686
PackageKit-gtk-module-0.6.6-2.fc13.x86_64
PackageKit-0.6.6-2.fc13.x86_64
PackageKit-device-rebind-0.6.6-2.fc13.x86_64
PackageKit-glib-0.6.6-2.fc13.x86_64
PackageKit-command-not-found-0.6.6-2.fc13.x86_64
PackageKit-yum-plugin-0.6.6-2.fc13.x86_64
PackageKit-yum-0.6.6-2.fc13.x86_64
PackageKit-gstreamer-plugin-0.6.6-2.fc13.x86_64

I uploaded an example of the codes here:
  * triggers INIT hook error: http://pastebin.com/Ht9JR8DX
  * triggers PRE or POST error: http://pastebin.com/NuhPbzFh

You can use them and run the gpk-application or the gpk-update-viewer to 
check the errors.

We have to hide some repositories  and make them available on the fly when 
specific users run yum or any front-end application to it .
We get the repos from a webservice and add them dynamically.

The GUI tools don't actually run yum or the plugin code, that's done
by the packagekitd daemon.

What version PackageKit and yum are you using? Could you upload your
yum plugin somewhere public also please.

It depends on how your plugin works. PackageKit does some things a
little bit different to yum.

No. PackageKit is doing different things with the data, and is
exporting it in a different way to using the bare yum api.

What's your use case for adding and removing repos like you're suggesting?
