Hi,

such a filter should work. I did not actually test it, but I inserted a

boost::iostream::flush(sink);

to one of my output filters and it compiles. Code is attached.

PS: The whole class is not very well tested, since we always use its 
input filter equivalent, but it should give you a start...
