This does something essentially equivalent to showoff.io if you have a publicly facing server...

show

# Usage: show <local-port> <subdomain>
function show() {
    DOMAIN=".webhostology.com"
    REMOTE="$2$DOMAIN"
    ssh -tR 8080:127.0.0.1:$1 vps "sudo ssh -Nl \$USER -L $REMOTE:80:127.0.0.1:8080 localhost"
}
