Come on! I am way more lazy than that! :) and remember I want to use
this
part in a cronjob, so I don't have to do it all the time--I usually name

it after the repo dir:

* */2 * * * REPO=whatever hg -R $REPO --ssh $REPO.ssh push -f
$DSTHOST/REPOS/$(basename $REPO)

The key here is that I have this little script that given a list of
repos,
for each it generates a dsa key and creates the .ssh file (with the 
embedded private key) and the authorized_keys data (with the publick
key), 
so the infrastructure is totally automatic--I just have to give my real
key
for the script to install the authorized_keys parts in the destination
hosts.

[soon to change to 'push -e $REPO.ssh...' by Matt's request]

To sum up: if we add it to the hgrc as a default, it is sweet, but it is
also
very useful to be able to override from the command line. I hope to have
it
ready next week.
