You should refrain from making comments about something you've clearly not given a serious try. Yes flash does not work as is with pulseaudio because its a *closed source* app which is abusing the alsa interface in many horrible ways.
Not working as is does not mean that it does not work though, Lennart has gone to many troubles to make it work. So all you need todo (on Fedora, other distros will have something similar) is: "yum install libflashsupport" and after that flash will work fine with pulse. Since you are manually installing flash anyways, having to install an additional package which helps integrate flash better into the system (it does more then just get pulse to work with flash) is really not all that much to ask.
