$25 is a lot of money, especially regarded the fact that it adds a functionality Apple should have provided in the first place. But then especially the latest version with the built-in video player does an excellent job. In fact, I've got fewer problems (none, exactly) with AirFoil than with Airtunes. Also, I got excellent, quick feedback with a working solution when AirFoil didn't work with my new Draft-N Airport Express base stations.
Even if it seems expensive at first, it does an excellent job and is well supported.

Gotta correct myself - Bwana /does/ nicely integrate with Firefox.

Program is open source, so no problem building a Universal Binary yourself.

BTW, if using Macports, add the following lines to /usr/share/misc/man.conf:

MANPATH /opt/local/share/man
MANPATH_MAP /opt/local/bin /opt/local/share/man

Incredible time-and-effort-saver. I've literally saved days in web development since I started using this plugin. And I don't even do front end stuff that often :-)
