This has already been covered ... git and hg integration is only partially 
functional. Git is a right pain in windows, while hg is at least functional 
identically in both linux and windows. BUT sub-repo is an area that is not 
currently supported in any of the integration tools and hg-git actually fails if 
there is a git sub-repo. Keeping each extension of php in it's own sub-repo is 
the obvious way of managing things, but is the very area that is not fully 
functional. Building a single 'download' of a group of packages is not something 
that can currently be handled, as the 'module' structure of CVS simply can't be 
mapped. A single CVS repo becomes 200+ separate repo's in hg or git, and you 
then need script files to manage things, which is fine for command line users, 
but a problem for the IDE approach.

Again you are missing the point here. CVS/SVN works nicely for managing a master 
code base. DVCS does not naturally support that, and this is a major area that 
needs to be managed by any project switching so that you CAN manage a master 
codebase. The problem I was trying to highlight was that with patches around a 
number of distributed copies, managing a 'rollback' can be difficult if several 
people have pushed around different paths, and currently the available tools do 
not allow the same flexibility that has been provided for CVS/SVN for several 
years.

Again ... there is no 'natural' workflow so it becomes a lot more difficult to 
cooperate. I still think that a 'master' of the CVS/SVN type may be preferable 
rather than trying to manage that via a DVCS maze? All of the projects that have 
published their research have indicated that there is not a simple answer and 
that the goal posts are still moving on a weekly basis? hg has published 
improvements to the sub-repo problem only this week, but the integration 
packages still have to catch up.
