corporate users will suffer from open end-to-end connectivity most, including tunnels that make it impossible to see what's happening.

Not really. It's possible to sniff encrypted tunnels if you know the private key of one host (and enterprise admins probably would know it), it's even supported in Wireshark.

Besides, it's not like I can't make an HTTPS tunnel which can pierce all but the most paranoid firewalls right now. Skype does this, for example.

Nitpick: that depends on the key exchange. Sniffing after a Diffie Helman requires the cooperation of one of the parties, and I don't think wireshark has support for this at the moment.

*sigh* that is one thing that is probably true, some network operators will break their networks in the name of security making life difficult for the people who use them and that won't really protect anything because so much traffic is tunneled over 80/443 which is almost universally allowed.

That's because it requires the "end" party to take the initiative. That's the beauty of NAT. Put an ancient totally unsupported bug-riddled system that every grandmother knows how to exploit remotely behind a nat firewall ...

And it's perfectly secure.

No it isn't. If that was true then most successful attacks today wouldn't even occur. For some time now the bulk of attacks have occurred over connections initiated by the end user system.
