Hey that's pretty nifty.  However, after running gprof on the fping
gmon.out, I get a nice callgraph analysis and such, but all the times
are listed as 0.00.  Weird.

gprof only measures time spent in user-mode. I think fping spends most
of its time inside the select() system-call waiting for data - that's why if you run it with "time" you'll see almost no time spent.
