    I hope to soon see something like:

    cat ~/message.txt | google mail --to "user@gmail.com" --subject "Awesome!"

You can do that now:

    aptitude install sendEmail
    alias google-mail='sendEmail -f myaddress@gmail.com \
    -s smtp.gmail.com:587 -xu username -xp password'

Then

    cat ~/message.txt | google-mail -t "user@gmail.com" -u "Awesome!"

Sure, pre-defined command would be nicer, but if you use VIM, I assume this isn't too much for you ;)
