Why do some people simply assume that if you lock your door when you leave
the house, that you're hiding something illegal inside?


Most people lock their door, but I don't know many people who take all
of the steps that you take. That's probably what Diesel was getting at.

What does Windows Networking have to do
with your browser creating a unique ID to use with a proxy?


Asking that is like asking:
"What does a warm coat have to do with winter weather?"


I thought it was a valid question. "Windows Networking" isn't
responsible for creating or storing either of the unique IDs in
question, and by the time they're being transported, the session is
encrypted.

Why in
the world would you think you could sniff it with wireshark when it's
most likely going to be an encrypted transmission?


That's like asking:
"Why in the world would you think that a warm coat will change the winter
weather when it's most likely to be the weather that is making you cold?"


Same as above. I think he's asking a valid question.

You seem to be a bit more than lost here...


What you call "lost" is that I'm asking a question that not only has never
been asked before, but that only a Windows expert could answer.


Essentially, what you're asking is:
1. What are the two unique IDs and where are they stored?
2. Can they be manipulated to gain more privacy?

For #2, it's difficult because they are in an encrypted session. You
don't have the right certificate that would allow you to decrypt the
session to see the values. I'm specifically referring to the one that's
supposedly generated on the fly by the Surfeasy site. The behavior of
that ID is similar to a session cookie in that it's generated by the
server on the first request, then sent to the client with the
expectation that the client will return it on each subsequent request.
It's stored in memory, but likely not on disk.

For #1, you might have seen examples back in July/August when you were
asking the same questions in alt.os.linux.
