"Return to Battlefield" Style World Border

I am looking for a world border plugin that lets me set a border (with something like worldedit) but instead of just killing you or teleporting you back it lets you keep walking, bringing up a 1.8 title that stays up as long as you are outside the border saying a customized message from the config.

While you are outside of the border you slowly take damage like when you are out of hunger and if you reach a certain amount of blocks away from the border you will be instantly killed.

There should be a config with...

Custom Message to go on the title when you are outside the border (allow colors).
(default RETURN TO MAP)

Distance to get from border to be insta-killed (default 100).

The commands should be...

/border set - Set the border

and /border [on/off] - Turn on or off the border.

 

Using worldguard's custom flags you can achieve that. Let me explain

B = Battlefield area
/ = Come back to battlefield area
# = Kill-area
########
#////////#
#//BBB//#
#//BBB//#
#////////#
########

In the region formed by the # you will set the command run from the console /kill <player>
In the region made of / you will set the command /title <player> etc
Google wg custom flags because now I'm really in rush and I cant find the link to the devbukkit page.
