The mentoring dynamic is a great way for all involved to further develop and realize potential. Constant communication should not be the focus, rather structured guidance. Sharing your insight and gathering feedback from your mentees about specific topics, and building a plan around how to communicate your overall message over a specific time period, is key. You are the lion, teaching your lioness's how to hunt, after you give them some of the basic tools you need to let them hunt and then re-group together on what does and does not work. Start simple, use Skype, it's free, and then as your program develops and you can invest into other technology. Mentor in small groups or waves, maybe initially starting with 5 or 10, then a couple months later maybe start another wave with small group and apply all that you learned from your first group mentor experience. You definitely have a lot to offer and I think you would be a great mentor .
