Indeed ... a frustration for many, including myself, who need specific pieces of functionality from larger projects that have larger schedules. We've been using a "dummy" NIC driver for the development of the Virtual Router project which should be coming online soon. I'm in the process of getting a legal approval for making the driver available sooner ... It's based on afe, which is already in the OpenSolaris repository, so I don't see any problems with making it available, but I need to check first. The intent of the driver, of course, is to bridge the gap until Crossbow Anchor VNICs appear in Nevada, so any long term dependency on the driver should be discouraged, but having to allocate hardware NICs for virtual interfaces in the mean time is certainly a more substantial discouragement.
