I need some hints as to what the above means, but combined with (3) it becomes 
trivial ...

You want self updating code running on *your* system ???

What do you mean by "safe virus" ??

If you take this step, you can chuck SKSP altogether.
All that is needed is some way to tell the virus to stop when teh answer has 
been found -- or would you not bother with that ?

If random searching were permitted, that would indeed be the way to go.

I'm lost -- if thee search is random, you kusst let it run !

Eh ?

With random searching you just run it on all machines you can !
No adaptation, jusst brute CPU cycles ....


Have I missed something ??
