@douglas:
it destroys the whole concept of urls - to know where you currently
are.
bookmarking, history etc - everything doesnt work anymore.
well, if you really want all that for an app - fine

but I am not convinced that "cloaking" urls adds any security.
the "params" of urls shoudnt be what you need to wry about.
its the content of them which should be secured. and this can be
achieved via simple ACL, as well.
if you focus all your effort on making urls unguessable instead of
clean ACL but someone is able
to get hold of it (sniffing, browser history, logging tools), the
result is even worse than
not having url encryption.
