This system actually works very well for me. At each site I have a
script like this: (watch the wrap)

#! /bin/ksh
MAILTO="michael.smith at thalesatm.com"
read COMMENT?"Enter delivery comment: "
hg commit -m "$COMMENT" .
APP=`basename $PWD`
case $APP in
    nixedit)
        slave=/data/smithm/remote/nixedit
        ;;
    *)
        echo $APP " is not recognised"
        ;;
esac
NUMBER=`date "+%G%m%d%H%M"`
echo "Sending changeset: $NUMBER"
echo "Comment: $COMMENT"
echo "Destination: $MAILTO"
CHANGESET="/tmp/$APP-changeset-$NUMBER.hg"
hg bundle $CHANGESET $slave
hg push $slave
sylpheed-claws --compose "mailto:$MAILTO?subject=[$APP] $COMMENT"
--attach $CHANGESET

...which creates a bundle and pushes to the reference repo. At the
other end I run:

#! /bin/ksh
INCOMING="$HOME/incoming"
for c in `ls $INCOMING/*.hg`
do
    filename=`basename $c`
    echo "Processing " $filename
    APP=`echo $filename | cut -d "-" -f 1`
    case $APP in
        nixedit)
            main=$HOME/src/nixedit
            slave=/data/smithm/remote/nixedit
            ;;
        *)
            echo $APP " is not recognised"
            exit 1
            ;;
    esac
    hg --repository $main unbundle $c
    hg --repository $main push $slave
    rm $c
done

...which looks for bundles, unpacks and deletes them. The case
statements allow me to easily define other parallel projects.
