Ditto, though I'm looking into autofs for an embedded project to deal
with user-supplied USB sticks.

nolock is fine if you're at home and the only one writing to a file.
tcp can slow accesses a little but deals with recovery better.  Don't
remember what async does.  I add noauto (only mount on my request) and
hard, which is best used to address the lost mount points problem.  Most
of my mounted dirs are for reading only (media, mostly) though a few I
write to.

Also, it's my understanding that NFSv4 is better at this than v3 and
earlier.  Most of my systems are now v4 and I seldom have lost mount
points anymore.
