There are some other hosting companies now offering a Roadmap of sorts, and it's a great idea to allow clients to be able to see the status of current projects that are already under developement.
Here is the software, http://interstateapp.com/
We actually use UserVoice as our roadmap of sorts.
We will also be doing more public announcements via our Blog to let customers know when certain things get shifted into development and when they are finished.
In the next 2 months we'll see how UserVoice + Blog works and based on feedback perhaps implement more of a very specific public roadmap that puts all development projects in order with ETA guidelines.
You won't be notified about changes to this idea.
