tried around a year ago to get ePo working with remote clients. turned out the data channel requirement was that their firewalls had to be open for those ports for this to occur. with clients roaming all over the world and sometimes on client networks, this is impossible.
anyone know if they've updated this in newer versions? seems like the client shoudl be able to make an outbound request for its updates, etc and receive the info back over that same channel.
