Would what you're doing right now be possible using canvas on the client side?
On second thought, that might make things much more complicated / slow, you'd have to write something that allowed clients to send back processed results to speed things up for future searches by other users.
I wonder if there's any desire for something like http://maprejuice.com/, but easily applicable to any processing task that needs to happen in realtime * , as mentioned in the previous paragraph.
* But also support cached results.
PS If/when your no.de server crashes, do you have to push again to get it to restart? I was having this problem the other day — it's annoying to have to add a space to a file, commit and push just to restart the server.
