NORDO and Flight Following question

I was talking with a friend the other day, and he posed an interesting
question to me.

I use flight following occasionally. It's a great service, and as a
VFR pilot I appreciate the (workload permitting) traffic advisories.
We were discussing this when my friend asked 'So, what do you do if you
have a radio failure?' I opened my mouth to answer, but then realized
that I wasn't sure.

Here's my thought process:

First, I figured 'easy, I'll just squawk 7600.' The controller will
understand. Then I thought about it a little more. If I'm out in
class E or G, I don't really need a radio, and there are plenty of
barnstormers still flying without. So, why squawk an emergency-type
code?

Second, I wavered. If I just stopped talking to the guy, I'm making
his life more difficult while he tries to contact me, and probably
annoying him. At best, he'd probably just write me off and his
interest in providing this service to future FF requesters might drop a
tiny bit. At worst... would some FAA guy meet me at the field and
start yelling?

We went back and forth. I did some research on the newsgroups, and I
found plenty of references to pilots just 'dropping off' flight
following and nobody caring, but I'm curious to find out not only what
experienced pilots would do, but also if anyone knows what the company
line is. I read the FAR/AIM stuff about FF, and it was just radio
terminology and a description of the service. I might not have looked
in the right place.

At one point, we discussed some sort of formula of squawking 7600,
hitting Ident, waiting a few seconds, then squawking 1200. At another
point, we thought just squawking 1200 would be enough, though that
sounds kinda rude.

So, what would you do? Thanks!
