Why is there no hi/lo declare online?

[GiantBuddha]

When I first moved from my home game to casinos and card clubs, I played all the games. But I was always disappointed that there was no high/low chip declare. There are so many angles and so much confusion in this game that I understand why it's not offered in casinos. But why hasn't it made an appearance on the internet yet? It seems that the logistics would be much simpler than in a live game.
