I have not heard of a modified star topology, a star is a star. I would say
have seriously changed the characteristics of the cable by placing sockets
its length. If the sockets were a normalized type (not come across cat5
sockets either) then I would say the idea would work. A normalized socket
the connection at the point of connection. I would say that stray capacity
worse enemy here, resulting in a sad lack of speed.
