streams in popoon are basically just PHP streams, see 
http://ch2.php.net/streams for the whole documentation about that.

you have to register a stream-scheme. Either with 
bx_global::streams_register("streamname"), which registers the stream 
bx_streams_streamname or via config.xml as

   <streams>
         <stream>portlet</stream>
     </streams>

There's nothign SAX based in Popoon. And yes, they are character-based. 
As said above, they are "native" PHP streams, nothing more fancy than that.

Maybe reading the PHP streams docu helps :) If not, just ask again
