Thanks, yes if you want to take this one on then that would be great.  BTW, 
I've checked and we have two complete hash table implementations in the 
Boost files section (http://groups.yahoo.com/group/boost/files/), IMO it's a 
pity one of these hasn't been brought up for review, but I guess the most 
important thing is to sort out the wrapping of existing std lib 
implementations.
