I've setup a new website at http://mcpe.crombz.com where your can publish your server for free. It is easy to use and does not require any kind of membership.
1- Visit http://mcpe.crombz.com with your browser from the network hosting your server
2- Enter a short description of your game
3- Enter the shared external port you have configure on your router
4- Set your status (Online/Offline)
That's it. The website will detect your external IP for you. Online servers will be listed up to 5 hours which should be enough to gather new players.
The website supports mobile devices like the iPod or the iPad so you can easily host a MInecraft Pocket Edition game, using only your mobile device (assuming that your router is sharing the device game over the internet)
