I'm trying to setup a pool for litecoin mining with support of the stratum protocol and VARDIFF (variable difficulty).

I read the answer of cdecker on the following question How to setup pushpool. This was quite helpful. I managed to setup pushpool and everthing is running quite well (at least I can see CGminer connected and doing something).

I'm just stuck in setting up startum and VARDIFF. I was searching through boards, but I can not find anything that is related to my problem. The only approach I read on bitcointalk was to use "rpc.target.bits" : 18 instead of "rpc.target.rewrite" : true in server.json to adjust the difficulty, but no success :( For VARDIFF I can not find anything at all.

Any help would be very much appreciated!
