I think someone has already pointed out netstrings, which will allow you 
to send arbitrary strings over network connections deterministically. 
I'm afraid for the rest it's just a matter of encoding your information 
in a way that you can decode without allowing a malicious sender to 
cause arbitrary code to be called.

The issue with pickle is that it's way too general a mechanism to be 
secure in open network applications, so a suggestion to beef up its 
security was misguided. Trying to "beef up pickle's security" is like 
trying to make a shotgun that can't kill anything.
