No, I wasn't suggesting that. Using an approach similar to the Java
"sandbox", you run a Java applet which connects (through the shell) to the
proxies to receive keyblocks. My main concern was generalising the type of
problem. Security has to addressed, sure. The generalised client can only
a) compute and b) talk over the network. No local disk access, etc. Runs at
a low priority...
