Mailslot alternative?

[DavidXanatos]

MSFT is going to retire remote mailslots: https://techcommunity.microsoft.com/t5/storage-at-microsoft/the-beginning-of-the-end-of-remote-mailslots/ba-p/3762048

I wonder if there is a alternative with similar characteristics, which would be:
no need to open an own network socket.

So some windows API that would use the latest and greatest samba or whatever to broadcast some data to all PC's on the network in a way that allows programs running there to receive it.
