crossbow discuss - Nov 2006 - Design review of IP Instances part of Crossbow

Erik,

One additional comment I meant to include is that I think it would be
useful to add a paragraph on what is possible today with the current
stack in terms of sharing a link versus what will be possible with IP
instances (using separate physical NICs or VLANs) versus what will be
possible once VNIC support is introduced.  Once VNICs are available,
there will be a lot more flexibility but until then, the use of IP
instances will be limited by the physical hardware or the use of
VLANs.
