They could easily do it for communications between gmail users... they just don't want to do it. > FWIW: As long as the email does not leave Google (i.e. an email between 2 gmail inboxes) it is actually already encrypted end-to-end (AFIAK). no, end-to-end means from user1-to-user2, not from user1-to-gmail and then from gmail-to-user2 (ie: gmail should never be able to see the content of your communications if it was truly end-to-end)
