Hmmmm, didn't seem to go the first try...

Lets see-saw...
1. chain saw

2. pole saw

3. saw attached to a drone... (have you seen the video of them trimming trees 
on a power line right of way from a helicopter?  Nasty!)

4. saw(or wire cutter) on a wire crawler that climbs the wire and cuts it at 
the top thus falling to an early death.  Something like this:

5. a wire saw (thin survival saw that coils up) tie long ropes on each side of 
it and put it over the problem wire.  pull the problem wire out as far as you 
can, even if you have to add rope to it to get the wire saw as high as 
possible.  Use the ropes on the wire saw to slide it up as far into the tree as 
you can, then use a sawing motion with the two ropes to cut the wire.  
depending on how high it is you could thread the problem wire through pvc 
conduit and keep adding sections to push the wire saw as far up as you can 
before cutting.
