Actually, that's not entirely accurate.
You can set cookies for multiple domains on one HTML page -- you simply have
to write a page that calls one image from each domain that you want to set a
cookie on, even if that image is nothing but a 1x1 transparent gif.
Cookie management and updating will be a challenge moving forth, but you
should get the result you're looking for.

right, you can't do it. the browser won't accept a cookie for a
domain other than the one it's coming from, and it won't send a
cookie for a domain other than the one that's being requested.
a couple of ideas for a workaround would be:
1) you can set a cookie on domain1, redirect to a page on domain2
which sets another cookie, redirects to domain6 and sets another
cookie and redirects back to domain1 (messy)
2) you can restructure your domains into subdomains like so:
www1.domain.com
www2.domain.com
www3.domain.com
these will all get and send cookies for domain 'domain.com'
