I got from a chat that the layers could be converted to movie
clips in flash and then accessed that way from flex. im new to
flex, so i dont know what is involved. this same chat said that
adobe is coming out with a product called thermo that could do
this, but it is not out yet.
Yes, you would use Flash currently to import to Flash, then
cut things up as needed. Make sure and set in your Flash
preferences for thing to be brought in as 'Editable Text' and
'Editable Paths', and import as Flash Layers.
The upcoming Adobe Thermo application (essentially Flash for
Flex with 2 way asset management) would probably handle PSD imports
when it arrives.
