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".

[ They had this long discussion about languages on #monotone the other 
  day, and the reason I'll take C over anything else any day is the fact 
  that a well-written C program is literally only limited by hardware, 
  never by the language. The poor python/perl guys may write things more 
  quickly, but when they hit a language wall, they hit it. 

  I think we've got an excellent data model, and handling even something 
  huge like the _whole_ history of mozilla doesn't look very daunting at 
  all. I just want to have a real test-case to motivate me to look at the 
  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 ;)
