what is the fate of this library?

Thanks for your interest! The previous version available at http://www.xmission.com/~turkanis/iostreams/. """""""""" I downloaded the library from the yahoo link you mentioned in the review request. When trying to use 'filtered_stream' I ran into some compilation issues (RedHat 9, g++ 3.3) and before looking into it I wanted to know the review status. Knowing that the library is in the review pipeline I will give it another try. Some time ago I developed simple iostream adapter 'library' that allows to wrap IO device (sockets, pipes, etc) in std::[i,o,io]stream that is very similar to your sink/source technique. One difference is that the adapter is a template class parameterized by the source/sink types. Since your library offers this functionality (plus much more) I am very pleased it will become part of boost soon. """""""""" A quick look your page is very interesting. (looks very cool) I was thinking (also) along the same lines for some work I am currently doing, but you beat me to it. Question, have you tried to combine the streaming with boost serialization?
