I wouldn't have thought a getAsync() would be useful - given that with a get, you would want to block on getting your result anyway as it performs no other useful function other than retrieving data (unlike put, remove, etc).

The streaming API is probably further away.  Implementing a getAsync() ought to be trivial.  Care to create a JIRA?
