It depends on your definition of flow based router. Cisco used to
build routers with a flow based cache many years ago, and the process
of installing a new entry in the cache was software based (example:
6500 with Sup1). It didn't work very well in the face of exhaustive
address space scanning, e.g. denial of service attacks and similar.

I suggest you ask your account team whether Juniper/Cisco plan to
build such device in the future...
