Doh, I think this was easier than I had convinced myself it should be.
A quick hint from the URL,
http://wiki.openvz.org/Venet
suggested to me that multiple interfaces could simply be configured.
So,
- SSH onto ProxVE virtualization host
- issue command, "vzctl set 101 --ipadd 192.168.100.101 --save"
- take a look at ProxVE web interface / overview for this virtual host, now it shows both IPs listed in comma-delimited fashion where it previously showed just one IP.
- start up the host, bingo, we have 2 virtual interfaces up and I can ping where I want to.
ie,
moa-2:~# vzctl enter 101
entered into CT 101
[root@moaweb /]# ifconfig -a

It seems, now my only problem is that the NFS server is denying me the permission to mount the export. A bit odd because I can do the mount from the ProxVE physical host.. the 192.168.100.0 subnet is trusted .. I don't quite follow. But I'll get there soon, I hope.
