This will not work, sure it may be possible that you could make a fake server. BUT, to run the update you still have to go to GAME -> Memory stick -> then to the update, This method is the same as downloading the update from sony site onto your computer but then to the memory stick, except it cuts out the middle man.
The update is ALWAYS stored on the MS in the GAME folder in a folder called UPDATE.
Nice i dea though
