CHMOD name sounds maybe too close to Unix chmod(1) though It was not
in my mind, It was use saying "change mode" with "mode" being
additionnal (meta) informations, outside the pure content

but ok, I won't mind to change to a 'standard' name, like using MODIFY
[though maybe modify sound it will modify the content ?]
Any other suggestions ?

I am planning to use Expire for exactly the same purpose, why Expire
(sent by the PUTing client) won't fit ?

Yes, but why not [not all, but all control/access/meta changes?] ? more
catch-all than X-Access ?

I was thinking that having one 'topical' header with some optional and
expandable keywords was more efficient and cleaner that multiplying
the headers, am I completly offbase ?

Maybe we could use the same protocol ?
