Assunto: Re: [Libbitcoin] Network namespace
It is called for by the road map, under the libbitcoin (bc) namespace:

The reason it was done in advance of splitting out the library was that
we encountered a naming conflict with libitcoin-protocol. Following
convention this library requires the namespace bc::protocol. The library
must be independent as it contains code that must be shared across
client and server. It also requires the libbitcoin dependency.

However libbitcoin (in the current bc::network namespace) contains a
class called "protocol" (and one called network). Creating the namespace
in advance of splitting out the library seemed the most straightforward
solution and advanced us on the road map.

Personally I'm not so concerned with namespaces in C++. The Boost
namespace organization works well. It's the using statement that is
hazardous (and should never be used in a header).
