I think the "natural" thing in Java would be to have an explicit
"offset" parameter in the write() and read() method.
That would make them look the most like the write and read from 
[In|Out]putStream.

I could, of course, just add write and read versions with an offset
to the methods that are already there, in the Java bindings.
Having those would also allow for simple implementations of
readv()/writev().
