The technical end is what's actually gonna be in there , but also it has to be easy enough to change or repair if something goes wrong. For example the battery energy source or um what if the chip , for whatever reason , breaks down after a certain amount of time , do you just replace it ? Um is there any um  because it may be in the same area with several other user interfaces , like for D_V_D_s , movies , whatever. Um does it have to have a a way of being segregated from the others , in a different frequency or something ?
Well I may be wrong here , but I'd been thinking of this device as being a a cheap mass-produced device. We're trying to sell four million of 'em ,
Mm.
um that's that's , you know , that's almost one in every tenth household or whatever it is. Um and I hadn't thought of it as being a reparable thing ,
