Download Play services are not used by the Download Play child application at all(the title which runs on the Download Play clients). This is used instead: APT:GetWirelessRebootInfo. The DLP-child is launched by the dlplay system-application the same way as any other system-application->system-application launching(besides using NSS:SetWirelessRebootInfo).
There can only be one session open for each individual DLP service at a time.

WirelessRebootPassphrase #
This 9-byte UDS passphrase is sent by the DLP host application to the DLP clients via DLPSRVR:SendWirelessRebootPassphrase. The dlplay client system-application then loads it via DLP:GetWirelessRebootPassphrase for setting the NS WirelessRebootInfo. Afterwards once launched, the DLP child application can then use APT:GetWirelessRebootInfo to load that data.
Normally this a randomly-generated ASCII hex string, however it can be arbitrary. These strings are less than 9-bytes for some titles, the unused bytes are cleared to zero. This is the passphrase for the new UDS network which will be used by the clients and host for communicating, once the DLP child titles on those clients launch. This entire 9-byte passphrase is passed directly to the UDS network connection/creation commands.
