There's two problems between what you and Bryan said - routing and
layer 2 traffic (like IPX). 

Routing is only as complicated as you make it. What you really want is
for the vpn peer to be your default route.  You can either have the
server push the default route option, or configure the client to set the
default route.

Layer 2 traffic, if you care about it, is solved by using tap mode

There's always a hybrid of course - you could allow or disallow certain
things when not using the vpn. e.g. if you allow web traffic without a
vpn setup, joe schmoe visitor can do 90% or more of what he does without
you needing to fuss with the VPN or even WEP keys. ssh and other
encrypted stuff you might allow sans vpn because it's already encrypted.
ICMP comes to mind too... all these complicated "should I..." questions
are what made me too lazy, and I just left WEP on (for rudimentary
authentication) and don't enforce VPN although I do use it myself from
time to time.
