I'd love to see a "Plugin Store", for lack of a better name.
Basically an app store for Indigo Plugins where developers -- both official (i.e. Perceptive Automation devs) and independent devs -- could hawk their Indigo plugin wares and make money.
In the case of Indy devs, I think it'd increase the chance that the plugin would be supported longer term. I also think it'd likely lead to a stronger plugin ecosystem overall because there's at least some additional incentive behind creating a plugin versus just creating a plugin to scratch your own itch as things are today.
For Perceptive, I think there'd be a number of benefits -- not the least of which being the ability to monetize the addition of device/technology support additions directly. Also the ability to more precisely allocate where your [likely very] limited time input is going so that it simultaneously helps/impacts the highest number of users (i.e. the stuff leading the polls in this vote thread) while also directly bringing in additional revenues.
Additionally, assuming PA facilitated the transactions, you guys could take a small percentage for the service -- and not to be discounted is that it should definitely help create a more robust and more broad feature-set of supported devices/technologies which just serves to make the actual Indigo app that much more valuable due to the robust ecosystem that would surround it.
The only downside is that it'd cost users, like me, some extra money -- but let's face it, I'm [we are] shelling out $xxx on irrigation controllers (vs the $20-30 for a digital timer), likely thousands of dollars on switches/lighting controls, hundreds on 'smart' thermostats, voice/automation devices like Echo, etc.. the list goes on and on. I'd be more than happy to pay $5-20+ for a well-done plugin to enhance the functionality of these technologies & devices and have them be more integrated into my system.
There are some features/plugins that I'd very likely pay a lot more for even, especially when the alternatives are writing it all ourselves or (eek) paying for Control4 or Crestron or similar...
FWIW, I'm thinking something pretty small/crude, not a huge "App Store" or anything terribly crazy -- likely just there's a SaaS offering or a open source offering that would get you 90% of the way there in terms of a "store for downloadable e-goods".
Just my 2cents!
