In the .gitmodules file you can use relative urls, e.g.
[submodule "smart_ptr"] path = libs/smart_ptr url = ../smart_ptr # url = http://github.com/boostorg/smart_ptr.git fetchRecurseSubmodules = on-demand
The protocol used to access the super-project boost is what will be used to retrieve the submodule projects. This might help with issues accessing the repositories, although the super-project will have to accessed via http/https (or whatever ports are open through the firewall).
This also makes the whole repository structure relocatable, e.g. a development team using boost can clone all the repositories to their local development server without having to modify the .gitmodules file in the boost super-project. Unfortunately, there's no good way I'm aware of to clone all the repositories as bare repositories. Maybe the latest changes in how git submodules are stored (i.e. under .git/modules) will help.
Oh right, you can! Currently, cloning bitbucket.org/boostorg/boost pulls the submodules from github. I changed it to use relative URLs instead. Thanks! Daniel
