[boost] Any interrest for zip/bzip2 iostreams ?

I have implement iostream wrappers around the zlib and bzip2 compression 
library. I emphasize that the zlib wrapper does not rely on gz methods and 
therefore it is not limited to file->buffer or buffer->file operation.

A simple example of the stream is as follows:

ostream& output; // suppose this reference is initialized

{
     zip_ostream zipper( output ); // creating a zipper on top of output
     // zipper behaves as any ostream
     zipper<<"hello";
     ...
} // when closed, the zipper is flushed.

That's it. Basically, these wrapper makes it very easy to add compression 
to existing applications. Any suggestions welcome :)

The demo application is in the yahoo files section, at
