I'm not sure the remarks regarding Flash (Flash Lite) are entirely accurate.
As an end user, anyone can download the Flash Lite "add-on", for free
without entering IMEI, etc... as long as your device is supported. To author
specifically for Flash Lite, one has to have bought Flash as it is not a
stand alone application.
As a carrier, like Cingular/ATT, there is a "per unit royalty for each
device that ships with the Flash Player". The exact price, I don't know.
