Depends on your municipality but in some places, yes, running _any_
cable through a vent is a violation.  Crossing through or streaming
along; either way can be illegal.  I didn't know it until recently when
the electrician I use mentioned it when discussing some of the work he's
come across in other homes. 

However, spaces around vents are apparently OK, at least where I live.
In my home there's a vent space for the furnace & hot water heater.  The
flue is only about a 4 or 5 inch diameter and the space is far bigger
than that.  Local code says it's OK to run low voltage cable in that
vent space.  I plan on doing that when we run CAT6 from the basement to
the 2nd floor.  We'll just take pains to keep it to the side so it
doesn't touch/vibrate against the flue.

Doesn't looka as nice but if you can't get into the walls, a problem I

had in my cabin where the walls were 6-inch logs, then it's better
than nothing.

Another alternative that worked for us was to use the return air vent.
Our router is in the basement, and my son has a PC on the second floor.
Instead of running the cable through the vent "grid" in his room, I
rerouted it in his room so the cable comes out of a wall plate.

Dunno if I broke any building codes doing this.
