I run my own pool that is public and I recived my first MON 25h after I started mining, it take time people and in the beginning it was 1 MON per block.
Now it's much higher and people get paid.

Also VTC will go up but you will get paid what you mine. Unless you stop mining while having less then minimum payout.
MON min 1.0 default.
VTC min 0.1 default.

Edit: The guy running http://www.cryptomasters.net/ made a simple script to check your outstanding VTC/MON for merged p2pool.
He got it running and I got it on my node too. 176.10.212.237:9174
