The answer looks good. For more information the users should just take a look to the existing plugins in Fuerte and "derive" their plugin based on these examples.

Hydro will released roughly at the end of next month.
At the same time Fuerte will be EOL which will imply that the buildfarm for Fuerte will be teared down.
That means that you will not even be able to release updated Debian packages for Fuerte anymore.
Therefore I would highly recommend not to spend any time for Fuerte.
Your time would be better spent implementing new plugins for Hydro and/or improve/bug fix the existing plugins.
