Yes, there is a vast potential market in the applications you mention.
As far as production goes I don't think that there is an intention to subcontract the construction.
NCTech do not of course make everything and outsource many of the components, but have been very selective in their suppliers and the shell and such are machined on a CNC machine.
There has been a great deal of interest from the Military, Police, Survey, etc. and especially those using HDS, so I think the reality is that demand is exceeding their initial estimates.
