I think I did play with a direct DHT Client as well as a cache-in-between the Blossom server and a local HTTP to IPFS Gateway with some aggressive catching headers (which gave me the best results as when the CDN evicts media, more often than not the bridge hits the cache instead of IPFS), but I'll revisit it for sure. And also play with your stuff, as if IPFS is enough Blossom becomes unnecessary.
