    Some more investigation.
    
    There are two kinds of avro.  Avro memory buffers (streams) and Avro datafiles.
    
    Most of the implementation of the Avro datafile handling is locked up in the private implementation of `avro-c`  (header reading, compression codecs, Avro sync markers).  As such the only way we can interact with that short of reimplementing large parts of it is to restrict ourselves to things that can provide a c `FILE*` reference to the datafile.
    
    The second case is much simpler to handle since it assumes a preshared Avro schema.

> This would be useful for streaming systems that need to consume or produce Avro in C/C++
