Why take it to aneighbour's when you have your two meters side by side?

daestrom has the right answer. It takes more like connecting a battery to
itself and trying to charge it.

(there is that darn battery analogy again...LOL)

I just figured it would look less fishy if two addresses were involved.
 

So I run my line through a step-up transformer to raise the voltage a
little (maybe 5%) then feed that to my neighbor.

Because it's in exact phase with the grid, I don't need expensive
equipment to *make it in phase* which is what you must do with any
alternative power source.

5% would be way too large. Draw the circuit out and you will find the 5%
output into a dead short (meter element only = bus bar with a small CT on
it)

Boost-Buck transformers are available with lots of taps that give you rather
fine control of the output voltage.  Further, they are cheap and efficient
because only a fraction of the system's energy actually flows through them.
They are always my choice for small voltage adjustments (such as converting 208
to 240 or 240>208).

That said, I am sure that there would be some bureaucratic barriers to doing
what you suggest:  Your neighbor would probably at least need to have a
plausible PV system with all of the usual inspections etc. etc. to be paid for
power at that (crazy) PV rate.
