There is no point in trying to correct you - you have clearly already
decided on your view of things.
Actually, a lot of traffic is already compressed - many html servers
transparently compress html pages, and things like jpg files are already
compressed. But there is plenty of scope for compressing other traffic
such as email, html headers, and even the ip packet envelopes. When
traffic is coming from or going to a particular program, it is often
inappropriate to compress it - that would mean adding compression as a
feature of every program. And for lots of network types, especially
trunks, it doesn't make sense to compress traffic - it would take too
much processor resources. But for some types of network, such as
dail-up modem links and vpns, compression has little cost and therefore
SSL is so hard to break that it can be considered unbreakable.
Try not to show your ignorance.
A very large proportion of crimes are committed with "inside" help -
either willing help, unwilling help, or unwitting help (people who are
simply fooled). If I wanted to crack people's access to bank sites,
then I would do it by some sort of social engineering - not brute force
encryption cracking of a public wifi spot. I can't say what would be
most cost-effective - bribing an ISP's employee, using blackmail,
writing a trojan, or sending phishing emails. Setting up a VPN service
would certainly be a good method - it is extremely easy to do, and there
are plenty of gullible people willing to try it.
Ah, a /paid/ service. That makes it /so/ much less likely that there
are con-artists behind the service, or corrupt employees, or accidental
security holes. Since they charge money, they /must/ be good!
Do I think it is hard to leave a computer on all the time? No, I don't
think it's hard - my Linux server in the cellar is only ever turned off
by power cuts. And I'm far from alone in that. My desktop is on almost
as much the time - even my windows desktop at work has an average of a
month or so between reboots. To be fair, I live in a relatively cold
country where we use electric heating - thus there is no electricity
charge in keeping them on.
I mean all traffic except the VPN tunnel itself. For a VPN to be
effective at hiding or securing your connection, every network packet
(and there are /lots/ of them) needs to pass through the tunnel.
