Multicast on a selective basis
I have task sequences for on-demand imaging of one machine via PXE and also for automatically imaging an entire lab of computers. Ideally, the automatic TS would acquire the image via multicast from the site DP but one-off OSD runs on a single machine would still use unicast. It would be very nice to see this option available without having to load the image twice on the DP and enable one for multicast.
One potential option here is to use the Multicast properties to require a minimum session size before starting e.g. 2. If that size is not met then the download will fallback to Unicast/HTTP. These settings are present in the ‘Enabled Scheduled Multicast’ UI. The session size option would also require a wait of minimum 1 minute

Maybe adding a task sequence variable to control this behavior? (e.g. SMSTSALLOWMCAST ?)
