I have to admit I got this idea when watching a video example of a instructor showing his method to draw a picture. The video was from the perspective from his eye since he was recording from Google Glass.
My idea is to use Google Glass with developers remote and local blended. This is only one way how an experienced developer may be remote and the junior onsite developers can be local working more direct with the client and giving solid help from the more senior developer who is remote.
Another way could be a local onsite senior developer with a group of offshore working to produce the solution under the direction of the onsite developer lead.
I think this style of development has a potential to work and here is why I think it will, I have with moderate success worked with voip and screen share and another developer, but something always seemed missing and I would get frustrated not knowing is the developer working or stuck etc.. There is something about seeing the constant view of what the other person is looking at that keeps it more connected and real that glass will bring to just voice and screen share. I understand you have to look away for a break or check email on another screen, these unannounced pauses and quite periods can causes a disconnect between the members of the joint session. I think this more connected interaction with glass and hangouts will add to the productivity and might be that missing piece that I get when doing the tradditional screen share and voip!
Now my disclaimer! you have to have a team that can work in peer programming environment, in my tenure I have come across multiple personalities and team dimensions and with out a peer programming team this will not work.
I could see this being a bigger idea where a collective group of ace developers offer time packages to companies for this scheduled peer remote mentoring. To think about it even at $1500 for google glass, it could be passed around to multiple developers on different days. Maybe this could be a scheduling and bidding service where the expert mentor and his reviews can command big bucks to tackle your hard coding problems??
