Recent Telepresence Robot Active High Pass Filter Work

My lack of posts has been due to a lack of having anything to post about. Im continuing work on a 40A ESC and making the Active High Pass Filter for it has been a daunting task. Im also working on writing a very complete argument about why a commercial telepresence robot is a viable investment in time and money.
Currently the paper covers the following rough topics and sub-topics:

A culture shift which makes the product acceptable
A. Television via the web
B. Radio via the web
C. Interactive Video Games Online (FPS, MMORPG)
D. Broadcast Yourself Services

Rapid Worldwide Deployment of Broadband Networks
A. The coming WIMAX revolution (I discuss a decent amount that has to do with Motorola and utilize their former CTO Padmasree Warrior, now Cisco's CTO)
B. Ev-Do

Rapid Communications Development

Global Economic Transition
A. Need for increased distance communications

Viability of Transportation Costs
A. Peak Oil
B. You can't run a jet turbine on electricity
C. Cost Analysis of current flight infrastructure

Proposed Implementation Path

Potential Future Uses
A. Remote Camera Man
B. Virtual travel
C. Special Event access at reduced rates
D. Distance presentations and meetings
E. Distance social interaction

I'm gathering a variety of audio and video resources, so hopefully the argument wont be a total bore.
I have also been adamant about building the ESC the right way because I think it will provide enlightening skills for later devices I want to make. The reason I am trying to make an active high-pass filter is so that I can control an RC car motor in both directions only using one input signal. An active high-pass filter is basically a way of turning on a switch once too much traffic is coming through a gate. So think of an annoying detour that you run into while driving. The detour is like an active high-pass filter because road work is being done where you want to drive so the transportation authorities only allow a small amount of traffic through and make the majority of the traffic go a different way. In the case of my ESC, causing the traffic to detour and allowing it to go the non-detour way will drive a motor forward and reverse using only one control line.
