Maybe just wait and see.
First FileMaker has to write an SDK and publish it.
Than developers for plugins have to use SDK and add something useful.
Than people have to try it.
And on the end, you can release a solution to client.
Now that FMPA 15 has landed, do we have any sense from FM, Inc. if/when this will happen?
Sorry, they didn't announce this.
But you can visit DevCon and ask someone.
