This wouldn't be too much of a problem with a remote character or byte
stream, especially since we've removed the single-character and
single-byte read().  AElfred, for example, slurps up 32K at a time
into its read buffer.

By the way, Java is simply the initial implementation for SAX, but it
is not intended to be the only one.  Ideally, I should have used
OMG-IDL from the start, but many more people understand (and can use)
Java, so I started there.  Several people have offered to write
OMG-IDL versions of the interfaces as soon as we're done defining
them.  There is already a Python implementation of an early draft of
the SAX interface, and I might take a stab at the C++ version myself.


All the best,


David
