Slush:
Do you considerate support getwork connections via port 80? I know that you want to shutdown them, but due to proxy limitations (whe i have some miners working), I only can reach 80 port. I put a mining proxy in a server at home, but my ISP changes the network and now my personal network can´t be reached by outside (only NATed connections). This was a kick in the balls for my. Can't connect vía VNC, have lowid in Emule, can't use mining proxy, can´t use remote emule, etc.
You could put up a proxy at home and translate port 80 to 8332 of your local proxy for stratum, if you wanted.
I have my proxy running on an odd port (not 80) and my internet workers bounce through there.
