I started this discussion to find out the best way to add
libflashsupport to netscape-flash for users who want the extra features
that it offers.

Yes, I considered this, it is option (2) in the original post in this
thread. However, I do not believe this is the best solution.  Consider
the case where:
 - A user has 'ssl' disabled globally
 - A user sees that netscape-flash now has 'ssl' support, so he/she
enables 'ssl' just for the netscape-flash ebuild.
 - The ebuild would then install libflashsupport, but do so without
actually adding ssl support, which would be quite frustrating to the
user, and probably generate unnedded bug traffic.

It would be much more clear to only use the ssl USE flag when it
actually affects ssl support.

I'm not sure I understand what you are saying here.
