Sure, no problem! In fact, I was wondering if it would be possible to
have a discussion about the overall networking strategy that will be put
in place for grub2 (and which is schedulled for the next release !).

As I understand, supporting the etherboot drivers is no longer the
primary option. As it is out of the question to have its own set of
driver,  the UNDI driver seems like a good idea. However, UNDI support
would constrain significantly the design of the network stack. In
particular, it defines a lot of structure such as dhcp header, ipv4
addresses and so on. It also involves interruption while it was assumed
previously that the interfaces would be polled.

There is also the option of calling etherboot from grub2, which seems
quite appealing but I think I don't really quite get that.
