Yes thats the plan, its working well on my boat but I dont want to put shomthing out their until all aspects are 100%, documentation etc.
I dont forsee any issues but would never assume that I get everything right first time, hence the trial. The process would be holding peoples hand with module swap outs if needed untill everyone is happy and everything is 100%, then make this version available to everyone.
If a bug is found we ship all five of you out replacement modules, and you send back the ones you taken out.
To put things into context I have got the backing of the company I work for, do this sort of design for a job and do this sort of thing for some very big international comanies, and they expect a solid product at the end of the trial. I would expect no different for this trial.
