Yes, the WKT input might can be changed to streams. I will think about 
that. Internally it uses Boost.Tokenizer. It takes a string as input.

To be clear: wkt-output uses streams already (from the beginning). It is 
a stream-manipulator.

WKB input is already based on stream iterators (though random access), 
contrary to WKT.
What is your reason to re-implement WKB using Boost.Spirit V3?
