Make sure your fingers are dry as well :)

Years ago I learned the trick of putting my fingers in hot water to see (?) how
close to boiling it is. It terrifies everyone who sees it and my wife shouts at
me. Heigh ho :)

Out HQ in Indiana (??) is 10x larger than our UK base. We have 5... uh, 
4 bases in the USA, but only one in the UK. This makes us a 
"multinational corporation". (Yes, you heard right.)

But it seems you have at least a rudimentary grasp of the concepts - have

What's the variance in site size?

IDK. AFAIK, the UK is "significantly" smaller than any other site.

Round numbers about how many people?  50, 100, 1000?

UK is 30 people, HQ is about 300. Don't know about the other sites.

That explains a lot about management's attitudes....small sites are very 
easy to not include in planning, especially when they're 10% the size of 
the main site.

That also makes it more challenging to be heard.

Oh, it's hard enough to make my voice heard within the UK site. The new 
UK management sees the IT guys at HQ as gods, and considers me to be 
little more than the tea boy. If I say one thing and HQ say another, I 
am always ignored. Actually, scrub that. I am always ignored. Everybody 
just assumes I don't know what I'm talking about.

On a coincidental note BBC2 had a Chinese cooking program on last night.  
Her tip for the best type of wok - carbon steel with a wooden handle;

That's a cool idea, but where's the fun in that? :)

Hmm... This part of the thread has strayed way off topic. o.O Just 
noticed the title had something to do with cryptography...

Wikipedia claims OpenVPN uses the OpenSSL library.

http://en.wikipedia.org/wiki/OpenVPN

Still unclear how it runs SSL over UDP...

http://openvpn.net/index.php/documentation/manuals/openvpn-21.html - 
under "Description":

"OpenVPN is tightly bound to the OpenSSL library, and derives much of its 
crypto capabilities from it."

From the above quote, it maybe doesn't, but instead uses the crypto from 
openSSL.

Well, if you consider going to the ER for burns fun, then have at it.  I 
have different ideas of what constitutes "fun", and not being burned is a 
part of all of them. ;-)

Oh no!  Thread drift! :-)

Then you need to make your voice heard.  Tell the auditor "HQ won't let 
me - I've tried telling them and they don't listen to me - so talk to 
them" and then wait.

One of two possible outcomes:  The boss will start listening to you, or 
the boss will get pissed off and sack you (which means you don't have to 
do the 6 month notice thing or find your own replacement, right?) so 
you're free to find something else to do.

Well, the documentation claims that OpenVPN is "an SSL VPN". But since 
SSL is defined to work over TCP... hmm. ;-)

A type O Rh + infused aluminium pan with a wooden base and a plastic  
handle with carbon steel insert.

Well, I've also seen other SSL VPN solutions that work quite well, I'm 
not sure as well how it handles it.
