Create wrapper for 1 or more standard crypto currency APIs about javamoney-shelter

Sounds like a good idea. While Xchange is built against Java 6, especially the Backports (the API should in theory work as far back as Java 6, I think there was no "Diamond" usage either) should work fine.

Yes, the API-BP has 1.6 so only in the BP of the RI there are references to Java 7. Creating e.g. an independent Android port should therefore work. And in real life most likely a lot of apps use Java 7 anyway.

I've implemented a basic version of this over in http://github.com/msgilligan/bitcoinj-addons.

BaseXChangeExchangeRateProvider.java does the heavy lifting: https://github.com/msgilligan/bitcoinj-addons/blob/master/bitcoinj-money/src/main/java/com/msgilligan/bitcoinj/money/BaseXChangeExchangeRateProvider.java

I started with wrapper classes for each exchange built on top of this, but I recently added DynamicXChangeRateProvider.java which can wrap any XChange provider specified by classname string: https://github.com/msgilligan/bitcoinj-addons/blob/master/bitcoinj-money/src/main/java/com/msgilligan/bitcoinj/money/DynamicXChangeRateProvider.java

I've also very-softly-launched OmniPortfolio which uses this stuff. The UI and the site need more work before I'll even consider it soft-launched, but there is a public-facing text-only website now.
