I know there are long-term plans to integrate the two systems but I've read nothing about this occurring anytime soon. The Florida systems (SunPass, E-PASS & LeeWay) use completely different technology than the E-ZPass System (including I-PASS, iZOOM) of the midwest and northeast. The only way I know of to allow each system to operate on the other system would be to retrofit every toll plaza with sensors from the other system. Not cheap.
