Thanks,

Under Styles you will find:

EmbedFonts: If you set the embedFonts property to true for a text field, you must specify a font for that text by using the font property of a TextFormat object that is applied to the text field. If the specified font is not embedded in the SWF file, the text is not displayed.

What might help is to try and animate not the bones, but the skins attached to them.
Also, according to Jeff (see comment above) the most recent version of OpenCOLLADA should work, so you can try and see if that solves anything.
And then there’s the option of using the AWD file format (see http://code.google.com/p/awd/). I’ve given that one quick try using preFab (http://www.closier.nl/prefab/), but that does not seem to export animations. I’m not sure if that’s to do with preFab or with the file format though.

As I mentioned, my frustration drove me back to the MD2 file format, which contains pretty much a timeline you can play back, and which works beautifully with the current release of Away3D.
I do realize that it does not give you bones to play with, but something you could feasibly try using this approach is to use multiple meshes. You can then animate those meshes together in your 3D scene and export them to separate MD2 files. You should be able to simply add each mesh to your view in Away3D to combine it all.

I would be very interested to know what turns out to work best for you, and what you find does not work. Please let me know how it works out.
