Well I'd suggest firewalling. 
The client host connected through the AP to the OpenVPN server does not
need to accept ANY connections on it's not encrypted interface, except
for the packets coming from the OpenVPN server (and maybe DNS, if you
use a hostname and not an IP address).
So you could use something like zone alarm and block any outgoing
connections that are not for the OpenVPN host on port 5000 (TCP/UDP
whatever you use) and block any incomming connections that are not
comming from the OpenVPN host (and not established (if using TCP)).
