ok, I understand your point of view.
I think 6 virtio and 6 nics is a good value.
Do you want I start write code on this basis ?
I can do code for new device syntax + hotplug, if it can help you.
(i'm sure you are very busy with all other parts of proxmox2 ;)

I want to avoid any additional configuration, because I want to keep it simple.

I assume that we can use the pci-to-pci' bridge soon. So we can simply map additional
device to the second bus.

I want to avoid new configuration option by all means. At least until you
show me that it is really required.
Having more than 6 network or disk devices is not the primary use case anyways? And it
would also be possible to use multifunction devices in future (not all users want
hotplug) for users who want a large number of network devices.
