Actually, I was considering some kind of simple compression (think RLE or some fast variant of Huffman/LZW), but for data payloads in messenger. That would help in inter-datacenter configurations (where fast, low-latency links are prohibitively expensive or even not an option at all, so any extra MB/s counts and latency is already high), and with slow internal networks (1gbit Ethernet, and so on), but never had time to do some proper research on that matter.
