Hi Simon,
I don't think your solution works always.
Look at your demands:
1) No GET encoded information.
2) No Session
So only POST (and COOKIE) remains to pass info around.
Both COOKIE and POST must be populated using Javascript (from a client
browsers viewpoint), and like Jerry said: that can be disabled.
I don't think you can solve this without using GET encoded info, or
demanding the visitor has JS enabled.
A more optimistic note: Learn SESSIONs, you will use them in almost any
mature webapp. So it is time well invested.
Best of luck,
Erwin Moller
