I've talked to some of the ops folks a bit, and we've already agreed that inline display of diffs is something we really need to add to Gerrit. I've filed a feature request to this end: http://code.google.com/p/gerrit/issues/detail?id=1137
It's worth pointing out that Google Code will let each of us indicate interest in this feature by clicking the little star next to the title.
If people are voting for bugs, please vote for this one as well:

It'll make the gerrit/labs access process less of a pain.
