First off, I vote for bumping serialization to the top of the review queue.
I've been using the library successfully in a development project for
several months now. While I have not exercised the more advanced facets as
some have, it works well with a complex mix of MFC, ATL, and boost libraries
including bind, crc, function, iterators, signals and spirit. I've been able
to serialize these to/from disk/clipboard/registry keys, etc. The only
difficulty left (I haven't yet tried serialization17) is xml string output
being rather verbose.

This topic has come up on the spirit list. Originally I was a proponent of
mmap approach based on experiencing major performance improvements with
earlier version of Windows particularly Windows CE. Today I've seen much
less difference in performance. I've been told that Windows 2K/Xp using NTFS
memorymaps files under the covers, and unless your actively adressing into
the memory range there's little to be gained, atleast on Windows. Perhaps
other os do this as well?

Any thoughts on future serialization of boost::function even being possible?
My use case is that I've a std::map of std::string/boost::function's that
provide user configurable filters that detemine what gets displayed in a
Table/List View. These currently are not being saved between sessions. It'd
be great to do mFilterMap & ar;

Robert, Thanks for the great job!!!
