Is it possible to get the spark to connect to a discovery server? Is this feature supported by any Newtek hardware yet? I haven't been able to find, well, anything about it aside from the handful of mentions in the developer docs and a video demo showing it in action for sources running on a computer with Access Manager.

If it can be done, I certainly haven't found a way yet. If not, when will it be added? It seems like a trivially easy thing to achieve, just a long-lived connection to the discovery server and a tiny string of XML (I may have tcpdumped the connection to see what was going on).
