[Lex Computer & Tech Group/LCTG] Comcast experimenting with hollow core fibre optics

 Correct. According to the specifications, they should be able to offer residential customers bandwidth more like fios. For whatever reason, every time I have asked to pay more money to get more speed they have turned me down.

 If Comcast practically could sell you more than 25MB per sec up stream residential today they would be offering it to people willing to pay for it, only they're not. I don't know of any residential Comcast customers that have more than 25MB up.

4.0 Is going to change things In such a way that it will become possible for them to realistically offer and deliver on higher upload speeds than what they are willing to offer today.

 Something is holding them back from offering residential customers higher bandwidth for a higher price today.
