Thanks for the feedback and suggestions for other services. Exactly what I was hoping for.

I have done work to abstract the logic to handle a text-tv service and it is pretty much done. I was able to switch from Yle text-tv to MTV3 by just defining a couple url's and regular expressions. My ultimate goal is that it can be done from the config file so that everyone can add/edit which text-tv's they would like to have.
