Well as a technology it's been fairly successful, but hugely expensive. The original objective was to be able to take sub-orbital missiles out and it's taken a long time to get anywhere close to that.
As for putting it into an F-35, I suspect you and I will be long dead before you see the technology miniaturized enough for that. The reason ABL is in a 747 is because it's basically a flying chemical factory. You need some scary $hit bubbling away in the back end with the appropriate voltages to fire it all up before you can go zapping anything. They have got a smaller version flying in a C-130 now, but it's a still a long way from dropping onto a pod on a fighter.
Fascinating stuff, but like Dai says, you have to wonder if it will survive in the current financial climate.
