1) That article is quite out of date, from Feb
2007.
2) The "improved method" talked about at the end is
actually what we currently have today with SWFObject. A couple of years ago,
SWFObject and UFO combined forces, and SWFObject 2.x is the result. We are
currently on 2.2.
We've talked about doing a bug-patch 2.3 release, but at
present the need for the release (ie, problems without workarounds) hasn't
justified the work to do so, so we're in a slowed down maintenance phase for the
time being.
As far as I (and I believe the other co-maintainers of the
project) am concerned, SWFObject 2.2 still represents the most robust,
standards-compliant, and flexible solution for SWF embedding.
We provide the markup-generator to assist web authors in
creating the best markup/code for their site scenario. We also have several
popular SWF-centric projects that we've coordinated compatibility with,
including SWFFit and others. We think this represents a solid and stable
ecosystem for SWF-in-HTML publishing use-cases.
