Hi
Looking at the json-rpc-api documentation, the listunspent call should accept "addresses" parameter, which in teory should filter unspent transactions for an specific address, but i cannot fine a way use it.
Via rpc, i allways get "{u'id': 3, u'result': None, u'error': {u'message': u'Expected type int, got str', u'code': -3}}"
I'm using version 1.0 alpha 15
