Sorry if this is a repost...

First, while I agree with you its important to keep this as open source as
possible there is a clear distinction that needs to be made between the
Flash IDE and Flex. Flex is a compiler and Flash is a design environment.
Typically when building any swf application artwork is created and placed
within the Flash IDE and then Flex is used to tie it all together. This is
made seamless by the use of shared libraries and components within the
ActionScript langauge. What I will suggest in this regard is to develop a
Flash player that's art is controlled via template which can be changed at
runtime. This is not too difficult to pull off but due to the nature of swf
will require the artwork to still be produced in Flash with the underlying
code all developed externally and can even be compiled externally (via
Flex). Another thing that can be noted is that Flex and Flash have different
sets of components available. Flash users typically have more robust
components available to them while Flex have more basic components. For
instance, with Flash 8 you get components for building FLV players that
allow you to merely drag and drop the components into your file and you have
a player. For Flex, the components must be built from scratch. So this
should also be considered.

To address the three parts of the project you listed:

1. The ActionScript Sound class only supports mp3. Therefore must be
converted to this format in order to play through swf.

2/3. In Flash, an FLV player is an FLV player. The difference between a live
stream and a pre-existing file is simply a parameter you would send the
player. Parameters can be passed in to swf via HTML or URL reference so you
can use the same swf file to drive the two sections.

I'm not sure if you've tackled the problem of converting to flv yet but I
have found that ffmpeg apparently will convert to FLV format. As for a
streaming flash server (which is required for live-tv) apparently there is a
project out there called Red5 (www.osflash.org/red5).
