I little bit modified openvpn package and add possibility to choose connection types and network limitations for each .conf
I put additional parameters in file Name.connections (where is Name same to Name.conf file in /etc/openvpn). It is look like:
================================
#Allowed connection types.
#CONNECTION_TYPE=GPRS
#CONNECTION_TYPE=WLAN_INFRA
#CONNECTION_TYPE=ANY #(default)
#CONNECTION_TYPE=GPRS WLAN_INFRA
#DENY_CONNECTION_TYPES=XXXX
#Allowed connection types.
#CONNECTION_NAME="AT&T Internet" PITT
#CONNECTION_NAME=PITT
#CONNECTION_NAME=ANY #(default)

DENY_CONNECTION_NAMES=myhome
====================================

If it is interesting I could build new openvpn package with modifications (on weekend only).
