Hi everyone,

Our OS X wallet "Hive" features an integrated application platform. We =
hope this will be a great way for folks new to Bitcoin to discover a =
variety of Bitcoin businesses, from exchanges, to merchants, to games. =
The applications are locally hosted HTML/JS, and generally feature the =
most stripped-down UIs possible. We display them in a =
mobile-proportioned WebKit frame inside of Hive itself. Transaction =
requests within apps trigger native Cocoa dialogue boxes and everything =
feels nicely integrated and secure.

Should Hive succeed in gaining a foothold, we hope that we may one day =
be able to sustain ourselves via an aggregate of very small fees on =
transactions within this app platform. We like the approach because it =
lets us stay focused on making Hive great, and keeping it free, but at =
the same time we recognize that it is a kind of obligatory middleman... =
With all that that implies? I'm not totally sure, and that's what the =
question is about.

Obviously there are a couple of brain-dead approaches: We could track =
what users do in the app, and send the business a bill (with blockchain =
proof, of course). Or, we could avoid troubling the business and have =
each user send a micro-transaction to some address of our choosing. The =
first one is messy and essentially makes us spyware. The second one is =
technically difficult, making a mess of transaction history, balances, =
and possibly in-app price listings. I'm not happy with either, but would =
lean towards the second one if I had to choose.

I'm not 100% sure if this is the appropriate venue for it, but before we =
make that decision, I wanted to state our intentions and see if I could =
get some fresher ideas in the door. We want to be as ethical and =
(ideally) decentralized as possible -- priorities #1 and #2 -- but are =
otherwise open-minded.

Some technical details for the curious:

1) Yes, everything will be free software under a GPL license -- =
including the app store and the apps themselves! That may seem to be =
risky given our proposed business model, but we are open-minded and =
think we very much welcome the 'competition' of a would-be forker / hope =
we can work together. ;-)

2) Although our BitcoinKit.framework supports both bitcoind and =
bitcoinj, we will be using bitcoinj with an integrated VM for the time =
being. The main draw is SPV, although to be honest we would prefer to =
support the network more via something like Peter Todd's partial UTXO =
sets idea (hint hint, anyone?).

We will be at the conference in Amsterdam on the 27th of this month if =
any of you want to meet and discuss.

Thanks for your time,
-wendell
