Instead of just one ping packet have an option to ping several times and only trigger down event if more then 1 or so fail. Also, it would be nice to have an option to keep sending the down event every so many minutes tell it comes back up.

there are 3 pings netwatch is making, and if none is successfull then it adopts some script actions to do.
If you want to make in the way you described you can use scripting based netwatch:
