Yes, but this is precisely for setups without ssh access. Only https and http.

Hmm. Repos, more like. Clones of repos, in fact. That does not sound
so unrelated to me.
Any details on hgserve's future you can point me to?

Wouldn't that basically just address bandwith issues? After all, if
disregarding size, I might as well just clone the whole thing and work
on the named branch I'm interested in. And I suppose the difference
between cloning a few parallel branches vs. just the branch I want is
not often going to be very noticeable compared to overall repo size.
More importantly, though, I have mainly the review scenario in mind. I
think patch review on a devel list has a lot of merits, but also a few
drawbacks. The fundamental one is that, depending on your mail client,
it can be cumbersome to get a patch into a temporary review repo. You
might want to do that to
- get more context for diffs,
- open a modified binary file with its native app (yes, we have .xls
files in our repo),
- run tools or tests on the patched state.
So what I want is a quick way to set up a temporary repo, push my
current work in there, and let people review. Since I usually use mq,
these repos are *not*stable*. You should not clone from them to
anywhere but maybe a local throwaway review repo. This gives
- a quick way to look at my changes without installing anything
(unlike sending bundles),
- a more sophisticated GUI for that quick look at my changes (files
overview, annotate, etc.),
- a quick way to pull my stuff into a local throwaway review repo
(unlike mail patch bombs).
Now if I could not only cheaply push my current state to a temp review
repo, but could cheaply create a review repo with versioned mq, then I
would give reviewers even more info. They would have the snapshot of
the latest state, and by looking at .hg/patches, they could see
history and changes to the patches, likely in reaction to issues the
reviewers brought up.
I guess the easiest approach to this would be to configure hgrc-rqinit
with hooks that automatically qpop -a, qpush -a on incoming
changegroups. Then there is no need for explicit mq commands in rexec,
and no dependency on mq as rqinit can be done as a simple `hg init
.hg/patches`, as Jesse pointed out.
