It wouldn't have all the features you want (number of shares submitted) but you could set something like this up with
MiningRigRentals. Sign up, and input your pool mining information, then point your miners to the MRR proxy. It's easy to change pool credentials on Mining Rig Rentals afterwards at any time.
Usually MRR is used for miners to rent their hashpower out to others, which often pays more than mining bitcoins directly. However if for some reason you didn't want to rent your hashpower out (I don't see why you wouldn't want to though) then you could just set a high renting price. IIRC Mining Rig Rentals supports all three of those algorithms too, so it would be a start to a solution for you.
Yeah, I'm looking to run a sub-pool, so it would be other people connecting too; not just me. They would need their own username/workers and what not, so I can track their contribution to the pool. I would then point everything to another pool, to do the actual mining. It's a new website I'm working on, that I don't want to give to many details about, as of right now. It's a different kind of pool, I'll just leave it at that.
Found this; but of course it's in Python which I don't know too well.
https://github.com/CryptoManiac/stratum-mining-proxyIt seems I could modify the last couple lines of stratum_listener.py and the _on_submit method in getwork_listener.py to add a database submission, but not entirely sure. It seems like the last few lines of jobs.py might also be of interest for a database submission; I really don't know.
It also doesn't support X11.
