Hi,
I use the Sena Pi to communicate with my husband while riding our horses. We have a friend that rides with us, and were hoping that we could get an additional unit for her, but I see that the Pi does not offer connectivity for more than 2 users. Since many of your helmet/communication options do offer multi rider connectivity, I was hoping you might upgrade the Pi to offer it, as well. We can't just purchase one of your helmets, because the helmets for horseback riding are different and not interchangeable with cycling helmets. Otherwise, you could collaborate with a helmet manufacturer, such as Troxel, and offer an equestrian version. I think you are missing out on a very lucrative market. Thanks, Judy
