Master: 
downstream-farmer talks to downstream-node. In order to use it, you'll need a node up and running. downstream-node requires MySQL and a working config, but this app, downstream-farmer, will require python-dev and libcrypto++-dev to install from source.
$ sudo apt-get install python-dev libcrypto++-dev
$ git clone -b devel https://github.com/Storj/downstream-farmer.git
$ cd downstream-farmer
$ pip install -r requirements.txt .
And connect to our test node by running:
$ downstream 'http://verify.driveshare.org'
This prototype performs three simple functions. It connects to the specified downstream-node, it requests a chunk (which also gives it the first chunk challenge), and then it answers the chunk challenge.
If this is at all confusing, we're doing it as a functional test in the travis.yml file, so watch it in action on Travis-CI.
Connects to a downstream compatible node. Should also generate a new account token and retrieves the heartbeat for the proof of storage.
connect(url)
Queries the server for a file chunk, which in this prototype is simply a file seed for RandomIO to generate.
get_chunk()
Answers the chunk contract that was retrieved with get_chunk().
