Google Compute Engine Service Accounts

External references, such as a standards document, or specification?

The Google Compute Engine service account auth is described here:
https://developers.google.com/compute/docs/authentication

Please describe the feature requested:
It would be nice to be able to use something similar to the existing App Engine 
identity credentials, to auth from compute using service account:
https://code.google.com/p/google-api-java-client/source/browse/google-api-client
-appengine/src/main/java/com/google/api/client/googleapis/extensions/appengine/a
uth/oauth2/AppIdentityCredential.java

A good implementation would have to track the token expiration and watch for 
request failure, in order refresh the token only when needed (as opposed to 
getting a new access token on each request).
