2) That sounds like a good idea
3) That sounds like a terrible design. I remember mentioning this a while back and then promptly forgot about it. XD How were you planning to attach the hinges to the base?
3) It is my intention to use pass-though hardware (black oxide, low profile allen-head bolts).
If I may be so bold as to make a couple of suggestions....?
erm.. perhaps I could make the rear feet smaller and incorporate a third in the center, it would look similar to this (but without the top-side profiling):
or... maybe change the location of the hinges, but that will alter the visual balance...
