Let's please move this discussion to the mailing list we set up to discuss 
this very subject.

The only reason we use one huge SVN repository today is because it was 
necessary in order to support copy-with-history across modules. That's 
the only showstopper. (BTW, when Linus criticised us for having the big 
repository, he forgot/didn't know about this factor)

I know Git can support it more or less easily and we have developer buy-in 
to that feature. I know that, given the nature of the thing, it's also 
possible in other DVCS, though I have no idea whether it's easy to 
implement or if it's a crude hack.

The one thing that the filesystem buys us is that we don't have to decide 
whether we split at kdelibs or the library; extragear, extragear/category 
or extragear/category/appname.

But we *can* decide on something. I made a proposal, Oswald made a 
different proposal. I think mine is workable: the split is at the tarball 
level (each main KDE module, plus koffice; kdesupport, extragear, 
playground and review are all "a collection of applications/libraries" 
each packaged individually and must build alone).

I see no technical reason to not switch to a DVCS. There's a lot of people 
who want to have a DVCS -- many are already using one. What's stopping us 
now is inertia and having people to do the actual conversion work.
