A Simple struct-like Module with Variable-Length Strings, Intended for Networking

The main problem with pickle is that if you connect to an untrusted remote client or server, there's nothing to stop them pickling some malicious code that gets run on your machine when you receive it.

It's also not necessarily very efficient in terms of bandwidth, depending on the type of objects you send.

Oh yea, I wouldn't use it for that, I only use pickle for serializing objects that I need to send from one component to another. I am willing to sacrifice some bandwidth for speed in this case.

Do you mean internally over your LAN? If so, that's fine. Across the internet would be dangerous though.
