I seriously question the wisdom of SunRPC. We want a situation where we can predict boundaries so that we can reliably read blocks or share them into the disk caches. Thus knowing the format is always read 128 bytes of header, process, think, read data block direct to disk cache. Rather than piecemeal scanning of headers to get to the data.
Sure it makes the protocol suck rocks over slow links, but on a slow link we can afford the compute time to compress/decompress it at another layer.
