I like this idea myself it's only right to compensate the developer for there time putting an app together.I myself have a android device and the app store is amazing and inexpensive i paid for apps that are worth .99 and some i paid for 5.00.
I guess vb.org can follow the same requirements that Android store use, to offer there 3rd party developer to host there app on there store rather it's free or paid...
And another neat option will be in admincp we can view the store and see what app's is available and we can choose to install it rather it's free or paid we can install it straight from the store.
some ways are better than others... i prefer vb.org without any commercial stuff... what would be good is a vb.net, which is missing... the .net is more for commercial goals, like coders/designers directory, marketplace etc...
