Would it be possible to sell BTC using in-app purchases on the Android market?

[k]

Just as the title says.

Create an app and release it on the android market for free. Anyone wanting to buy bitcoins could download the app, enter their bitcoin receiving address, pay for them using an in-app purchase and the app developer sends the bitcoins to the supplied address. Not sure if you can dynamically change the price in an in-app purchase but if not there could be a fixed purchase price in $ or whatever and the number of bitcoins sent would vary depending on the exchange rate. The seller would add at least a 30% premium to cover the 30% transaction fee charged by Google but I think there could still be a demand even with this premium due to the convenience.

Technically possible without a problem, but i wonder who is willing to pay additional 30% of the price to google?

For small amounts people might especially if they are new to bitcoins and just want to get some quickly and easily to test bitcoin out.
The 30% premium is probably less than premium on some of the buying bitcoins through SMS options. Also what is the premium on buying bitcoins through linden dollars on some of the exchanges?
