Freud puts patient privacy and the development of the science in conflict. If a patient does not trust that his or her unprocessed thoughts and emotions are kept secret, the patient may censor them by what can harm his or her reputation. If abstract findings are not shared with a scientific community, the ability of a therapist to help a specific patient diminishes.
1) The patient needs the therapist to be the hub of many secrets, and the therapy to based on experience with other people's secrets. In this sense the patient agrees to a scientific study of the anonymous abstractions from the private therapy sessions of many patients. Then anonymity becomes the issue, not privacy.
2) People already share so much online, and right now they do it for facebook's advertisers to be able to deliver them with better ads. The same behavior that is encouraged by consumer culture can be used for good, with the patient's benefit in mind.
So, in my view:
1) Shared psychotherapy information should be anonymous. Not easy as it sounds.
2) Current technological standards should be adopted, as long as the ethical question is "how to help the patient?".
