I commit often, rewrite mercilessly, and thus I push to the big server infrequently. I do push frequently between local machines and servers. Mercurial Evolve makes propagating these edited commits across my local servers quite nice.

Anyways, besides the plug for hg, my point was that I would expect pushing could be a once-a-day kind of thing, whereas commits should be every five minutes. :-)

I agree. Pushing too frequently means you can't rebase and reorganize your commits - unless you each use separate repos.
