VPN Initial Connection Problem

Hey everyone. I have a problem, but it may be my lack of understanding that is the cause. Ok so I attend a technical school, and needless to say there's a lot of wannabe hackers, pranksters and what not.

So from my laptop I'd like to connect to the wireless AP's around campus, but security is a concern of mine. So I'd like to use SSH to create a tunnel to the AP, and back to my house where I have an 'always on' connection. The whereabouts of my location doesn't matter, I'm doing it more just to have a secure connection to the wifi access point, from potential wireshark captures and man in the middle attacks.

My problem is thus, I want to do an ssh user@hostaddress -D 8080 from the terminal. This says create a secure connection to my user at my home address, and put all traffic through port 8080. But I can't execute this because my school has one of those "Login to use wifi" pages. Where you must supply your credentials that you are a student before any connections can be made.

So I'd have to put in my student ID and password, before I can even set up the tunnel to the wifi. This isn't just with my school, it's also at starbucks. You must supply a password to their wifi, unencrypted, before you can set up the vpn to the AP. This first initial step may seem trivial, but it's the kind of thing I want to avoid. Is there anyway to set up the vpn to the AP before having to prove my access to the login page?

NAME
corkscrew - Tunnel TCP connections through HTTP proxies SYNOPSIS
corkscrew PROXY PROXYPORT TARGETHOST TARGETPORT [AUTH_FILE] DESCRIPTION
corkscrew is a simple tool to tunnel TCP connections through an HTTP proxy supporting the CONNECT method. It reads stdin and writes to std- out during the connection, just like netcat. It can be used for instance to connect to an SSH server running on a remote 443 port through a strict HTTPS proxy. PROXY The name of the host running the HTTP proxy. PROXYPORT The port on which to connect on the proxy. TARGET The host to reach through the proxy. TARGETPORT The port to connect to on the target host. AUTH_ FILE The auth file is made of one single line containing your username and password in the form username:password OPTIONS
None. EXAMPLES
The common usage of corkscrew is to put the following line in ~/.ssh/ssh_config: ProxyCommand corkscrew proxy proxyport %h %p [<path to auth_file>] This will let the ssh connection go through the proxy with the help of corkscrew. ENVIRONMENT
None. FILES
