How do I set up a fee for my p2pool node? I'm running a p2pool node for dogecoin.

Since running the node costs me some money, I set up a small fee with

./run_p2pool.py --give-author 0 --net dogecoin -f 0.5 -a DSomeDogeAddressIOwn DOGEUSER DOGEPW 


but I don't seem to get any fees.
The local hashrate is around 10 MH/s, so I should get at least a few dogecoins.

Basically I used this setup: http://doges.org/index.php/topic,5586.0.html

It is running on an Ubuntu 12.04 Server, everything else works.
When I use the webinterface, "http://example.com:22550/fee" displays '0.5' as expected

Am I missing something?
Found out why I'm not seeing the fees:
The fee payouts are of type 'mined' so in the client history, they don't show up with an address.

Told me that there must have come some coins in.
Wow, such joy!

Edit:
seems like the new client shows to which address it was mined.
