Thought I would leap in here regarding the Looking to the Future: Indigo Up-to-Date blog post: Seems like an excellent way forward to me.
I like the idea that it should give Matt and Jay a more consistent revenue stream.
At the same time it means that Indigo Users will get more frequent and timely updates without having to wait for updates to be batched up for a new major release which is where I think we are at the moment with the pending release of Indigo 7.
Good luck guys ; you certainly have my buy-in to the new way forward
