Thanks for the feedback. We aren't using OpenVPN itself really, just
standard SOCKS for TCP, and then UDP tunneled inside of that SOCKS
connection using this udpgw-client/daemon system.

The VPN code that is part of the solution is more of a local loopback
capability for Android that allows us to intercept that packets.
