A plugin example for pie written in Python. Note: pyjsonrpc doesn;t work well with ID's of 0, needed to mod source to get it to work.

# pyjsonrpc has a bug in that it does not support id's of 0, you will need to modify it to work, change lines 214 in rpclib.py from:

```
    for response in responses:
        if response.id:
            responses_.append(response.to_dict())
    responses = responses_
```

# To:

```
    for response in responses:
        if response.id != None:
            responses_.append(response.to_dict())
    responses = responses_
```
