It would be most unfortunate technical progress
being hindered by such approach.

LZO is absolutely undocumented and its code is one big mess
(but works).

AFAIK Markus Oberhumer can't be reached
for long time by anybody.

I guess this will happen. There are few very promissing
compression technologies (say LZMA) around and
lot of good implementations of proven ones.

This also lead me to question: is there example of any
encryption/decryption filter in Iostreams?
There are quite many of them in C++, each using their
own conventions and it may happen someone will
normalize them to be useable within Iostreams.
