Looks like a really nice idea, but I share the glaziers' concerns,
think you're looking at 12mm laminate there (guess), sounds expensive
but do- able. Consider approaching glass suppliers specialising in
glass staircases.

If you're prepared to spend on the glass then I reckon the bracketing
is do- able, but again custom made and sunk into the plaster of the
wall.

I've uploaded another design [top middle] with various bracket styles
http://www.numero.co.uk/misc/loungetv2.gif
Thought top left was by far the kewlst looking, but reckon top middle may
come a close second, and the cantilevered section is reduced from
300mm to 141mm, nice one. Still don't know if I'd trust it with just 6mm
toughened though :-).

Just for the glass (original top left), I was quoted £104 for 4 pieces of
6mm, £140 if toughened and £164 for 10mm glass (although he was
very concerned about the latter, especially without good supports).
Initial thought this was a good price for 10mm, but then reading between
the lines reckoned it wasn't toughened which I think would be a bit scary. I
don't have any guidelines or formulae for using glass in this way, my
feelings are just that, but I'd still be heading toward the thicker stuff &
either toughened or laminated. Lam may be cheaper and I don't think the
polymer seam would be ugly in a polished edge.

My thoughts for fixing were for a solid wall and just a single shelf so this
may not be for you:
1. Remove plaster in a 50mm slot where shelf is to go.
2. Fix 20mm aluminium angle to wall along the bearing length with glass -
using say 4 strong rawlplugs and with vertical slots drilled in the angle
instead of holes to let you finely adjust the bracket position.
3. Adjust aluminium angle to get glass as flat as poss & then bed in glass
using high modulus (rigid) neutral cure silicone (black?).
4. Add another length of angle along the wall on top of the glass (again in
silicone) to take the cantilever load. Prob fewer fixings reqd but again slot
holes to adjust.
5. Re plaster above & below shelf to make a hidden fixing.

Now you are going to tell me it is a stud wall . . . and this was more work
than you were looking for :-)
