python - How to store already-compressed data in ZIP-format?

Question

I have a program, that collects logs from a multitude of machines (over Paramiko), and compresses them into a single ZIP-file. (ZIP-format is used -- despite not being as space-efficient -- because it can be "opened" by unsophisticated users with the plain "Windows Explorer".)

The machines are many and the logs are (sometimes) quite large, so the collecting machine becomes the bottleneck compressing them. Even if I parallelize the compression on the collecting-side, it will still be a bottleneck, because the number of servers is (much) larger, than the number of cores I have.

So, naturally, I'd like servers to perform the compression themselves before sending -- and then simply archive the data received from them. (Network-transfers will be sped up too.)

How can I tell the zipfile.writestr(), that the data given to it is already compressed?

If not zipfile, perhaps, some other module can do this?
