I was thinking about my own pool as well, but no free time available.
I tried xptProxy, found 6 tuple, but no money came, did not look further.
Hopefully in the future.
Just a reminder - running a closed source software - you have to trust the vendor.
It can produce any output vendor wants, and it can send the money anywhere - there is already a code for that while dealing with dev fee donation - check
https://github.com/gatra/fastrie/blob/stratum/xptMiner/xptMiner/main.cpp#L234 (I remember other parts/addresses, maybe a different code).
I am not accusing anybody, just stating the facts.
