Speaking of pproxies.. I just made up a perl script which automatically alters the ipaddress= line to different keymasters if it detects the buff-in (pprc5in.rc5) is low on blocks. My pproxy will now check it's buff-in every five minutes, if it goes well below the minkeysready (signifying Mika's is having block problems), it changes the .INI to D.Net's keyservers, sets minkeysdone and maxkeysdone to a high number, kill -HUP's the pproxy, kill -ALRM's the pproxy, and away it goes! When it detects it has a safe amount of blocks, it switches the ipaddress= back over to Mika's and resets the above process. Way cool!
BTW, I should explain kind of what min/maxkeysdone does, it means the pproxy will store all outgoing blocks until Mika's is back in operation. This way no blocks are sent directly to D.Net and your stats are safe on Mika's!
