Yes. Anyway, I think we'll get git working well for repositories that size, and eventually the core developers will notice how much better it is.

In the meantime, the fact that git-cvsimport can be done incrementally means that once we have the silly pack-file-mapping details worked out, it should be perfectly fine to run the 3-day import just once, and then work on it incrementally afterwards without any real problems.

So people like you who want to work on it off-line using a distributed system _can_ do so, realistically. Maybe not practically _today_, but I don't think the git issues are serious enough that we'd be talking about "months from now", but more of a "in a week or so we migh have something that works fine for your case".

  quickly, but when they hit a language wall, they hit it.

  huge like the _whole_ history of mozilla doesn't look very daunting at

  problems. ]

Sure. I actually just have regular 128kbps DSL myself. I guess I should upgrade to 256 (the downside of having deer munching on the roses in our back yard is that I don't think I even have the option for anything faster), but I'm so damn well distributed that the slow 128kbps is actually more than enough - everything serious I do is local anyway.

So it will take me quite some time to download 2GB+, regardless of how fat a pipe the other end has ;)
