Dave,
First off, let me thank you very very very much for your script work. Tokamak was exactly the type of solution I needed, as I use multiple VMnets to do work in demonstrating via VMware firewall/VPN, IPS and SSL VPN solutions, including a fake Internet load balancing component. I created a script of my own called ip-redux.sh that re-ifconfigs my interfaces for now, since I too need to have an address other than .1 on the Mac, as that is used by my other VMs. I would like to know in what way we can support you in your further work on these, including PayPal donations, since VMware has not, and in Fusion 2 at least, will not provide the required functionality equivalent to VMware Workstation in Windows.
Secondly, I'd like to put forth my wish list - if I have time I'll try to rework the scripts myself and provide you with "patches" that work for me. Alas, I never have enough time to tinker in bash on my Mac.
1. The ability to disable the DHCP server and/or NAT for any given interface.
2. The ability to configure a specific IP other than .1 for any given vmnet interface and have it stick.
3. The ability to create vmnets that don't even necessarily require an IP for the Mac itself (VMs talking to each other but not OS X).
Many many thanks again, and feel free to contact me or post here if you have any questions whatsoever.
