I like the idea of having a "Market" place for BE Themes and other BE related products.
Once there is a steady place to host all of these items and developers get some kind of a fee from the products they develop BE will
see alot more products than what we currently see.
Since these products would be "paid" products some level of support should also be included with the price of these products like free updates for a year, and etc.
I could see some type of a subscription product too like for $3 dollars a month / $25 per year (discount for yearly subscription) that would offer a certain amount of themes, extensions and etc to download per month, and with this subscription you receive a
higher level of support when compared with single purchased items.
Support could also be in the form of credit hours to have custom design or code work done to a theme or other products.
Like with a Basic member subscription for $3 dollars per month you get 2 hours of credit to use towards troubleshooting or custom work on a theme.
On a monthly plan have a use it or lose it policy for that month, yearly plan would get the hours credited to the customer account for an entire year so 24 hours in total.
How the customer want to use those hours are up to them, Support, troubleshooting, custom design or work on the product.
If possible one day have market places have a feed of their products that can be added to the DnBEGallery
have a service on DnBEGallery that collects all of these feeds and put them into one feed for the Admin Panel of BE to access.
This way a BE user can just go to their Admin area --> custom --> Market Place
From there it shows a list of all of the items available to buy.
That page can also have a category list of Themes, Extensions, Widgets, and Modules
User can preview the item and if they like it click "Buy" and be directed to the payment page all from with in BE.
Sort of like an "In-App" purchase from mobile apps like for iPad and etc.
Can even offer live chat support from with in the BE Admin area.
Also the products should also offer some type of an "auto" update feature where you can update the products as long you are still within the free support time frame or a member.
Just some ideas to get things rolling!
