The way this works is that once we have an account on your bug
tracker, we will sync comments from the GCC Bugzilla to Launchpad and
create a "see also" link to our bug on your bug.  Without the account,
we will keep the Launchpad bug in sync with your upstream tracker
status only.  With the account, we will pull comments from your bug
into the Launchpad bug.  We do not automatically sync any comments or
attachments on the Launchpad bug back to the GCC bugzilla.  We do
provide a "Reply on GCC Bugzilla" link on imported comments, so
someone can watch the activity on the Launchpad bug and comment
upstream from our bug if they need to do so.  If someone does this,
the comment from Launchpad is listed as from the user "Launchpad" (or
whatever we call the Launchpad account on your tracker that I setup),
and the comment also has "Foo Bar added the following comment to
Launchpad bug report XXX" at the top of the comment.

Some examples:

== Typical Bug Linked with Imported Upstream Comments ==

Launchpad: https://bugs.launchpad.net/firefox/+bug/394912
Mozilla: https://bugzilla.mozilla.org/show_bug.cgi?id=488605

== Bug Linked where Launchpad users commented upstream ==

Launchpad: https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/10910?comments=all
Mozilla: https://bugzilla.mozilla.org/show_bug.cgi?id=147419


I believe this will work in the way the covers everyones concerns.
Please let me know if there are other concerns.  If not, I would like
to go ahead and set this up.

Cheers,
