If ICE doesn't want that much IP available for free, consider seeing if you can sell it as an add-on to ERA or something. It's pretty slick.
ERA already has all the spell descriptions and parameters.
When a character is added to an adventure, the GM can check the information in the automatic and non-automatic spell casting actions.
The player also gets to have all this information from a smartphone/tablet using the character status module. They can filter a spell by name, list and description. All the parameters are also shown, and the player can check the required roll to succeed, depending on the number of preparation rounds.
As regards the IP issue, I think that ICE will not allow the content of all spell descriptions to be distributed for free. Still, you should contact them to see if there is some middle ground that you can reach with them, so that those who would benefit from your work can access it.
