Hello Beman,

looks interesting. I'm not able to find the bootstrap.sh file mentioned 
in the README, it seems to be missing in the repository.

I have four remarks on the current state

1) I think having the in-memory representation to be identical to the 
on-disk representation is a very serious limitation. Wrapping around it 
by overloading the output stream operators doesn't seem efficient. I'm 
not advocating Boost.Serialization; rather something like Asio's 
buffer-handling mechanism (which, in turn, can handle Boost.Serialization).

2) using a "path" argument to having a file open presumes a real 
underlying file. Although this is fine, maybe I would like to use an 
fstream?

3) It would be nice if it would work with an asynchronous file-like 
services, like, e.g., Asio's RandomAccessHandleService, see 
http://www.boost.org/doc/libs/1_46_0/doc/html/boost_asio/reference/RandomAccessHandleService.html

4) have you looked at http://goo.gl/r8Z2m and/or http://goo.gl/lvc9A ?

Thanks,
Cheers,

Rutger
