Les,

I beg to differ.

Nope. I meant to say that having support for flex-algo and FAD I can think
of new applications without need to write a new router's code (assuming
existing code is flexible enough :).

After all, aren't we in the era of network programming ?

See above.

And I will perhaps say it again that to me flex-algo is more of a mechanism
to build new applications then NEW APPLICATION itself.

That is why if we would adhere well to ASLA architecture there should be
many more bits for it then one.

Thx,
