it's possible, yes. you'd need to reissue new branch certs with the new 
names, and delete branch certs with the old names. there's no command to 
do this at the moment. it's possible to add one. doing it by hand at the 
moment would be a bit of a pain, unfortunately; the cert values (branch 
names) are all base64 encoded (with a trailing \n), so you need to do 
something awful like:

FROM=$(echo -n $OLD_BRANCH | mimencode)
IDS=$(monotone debug "$(printf "select id from manifest_certs where 
name='branch' and value='%s\n'" $FROM)" | grep -v row)
monotone debug "$(printf "delete from manifest_certs where name='branch' 
and value='%s\n'" $FROM)"
for i in $IDS
do
        monotone cert manifest manifest $i branch $NEW_BRANCH
done

it'll probably be more sensible to make a "monotone branch rename" 
command which does this internally, since it's so awful.
