How to share memory buffer across sessions in Django?

I want to have one party (or more) sends a stream of data via HTTP request(s). Other parties will be able to receive the same stream of data in almost real-time.

The data stream should be accessible across sessions (according to access control list).

How can I do this in Django? If possible I would like to avoid database access and use in memory buffer (along with some synchronization mechanism)

From stackoverflow

• Use posix_ipc or sysv_ipc to use shared memory.
