if you are using linux + tomato/dd-wrt/etc router as an openvpn client to connect to airvpn's servers and you want a permanent /etc/resolv.conf solution; edit your /etc/dhcp/dhclient.conf file on the computers that are connected to that router. comment out "send host-name = gethostname();" so it looks like "#send host-name = gethostname();". next add "supersede domain-name-servers 10.8.0.1;" to the file, replace 10.8.0.1 with whichever dns server you use. reboot your computer. check your /etc/resolv.conf file after rebooting and establishing an internet connection and you should see the replacement dns/domain servers...
