Edit: I came off more negative then I intended. I really love the idea, I am just a bit confused and number about it being locked up as an app.
I'll just add two quick things - First, we have the ability to create a more unique and interesting experience on a native application than via the web. For example, we can access a fan's iTunes library and Facebook with just one click. Thats pretty much impossible on the web. Second, this is just our first product. We plan to bring Merchbar everywhere, hopefully one day somewhere you'll love it.
Merchnow has a great collection of indie artists- will work to find a way to partner with them.
But you can do it wrong. Too many pushes for one. Or asking too abruptly.
