We're happy to assist prospective users in addressing their issues.  
As you observe, this library is not trivial (a reflection that the  
area it addresses is much less straightforward than many people  
imagine - as I did before really examining the subtleties). We have  
tried to make it easy to use for simple use cases, but implementation  
of custom unit systems, conversions, etc.. requires some  
understanding of the implementation.

C++0X auto and typeof will dramatically ease definition of new units  
and quantities...

The downside to touch typing is when your kinetic memory gets  
programmed incorrectly, it becomes really easy to quickly type  
specific misspellings - thanks for noting this.
