Yes, Tymeac standard edition supports call-back programmatically. That is, Tymeac does not limit call-back to RMI. Tymeac provides an Asynchronous Request, (schedule the request and do not wait for it to complete).
Within the request is how to contact the client when the request completes. Upon request completion, Tymeac schedules an Agent. It is within this Agent that one may put the code to perform a call-back either with RMI or any other method.
See our example of an Asynchronous Request. More.
