Thanks guys for the answers. 

I think definately SMT. 

I also think that if I can score and tap the redundant glass away then
any shapes required should be fine. 

With regard to drilling, I think this represents the biggest
challenge. I have two theories. One is to run the other way and design
as much as I can that does not need any holes. Then holes that are
required will most likely be done by hand after an accurate position
score point is generated for positioning. 

Heating I think will not be an issue if I use a reflow oven style
curve and heat things gently. 

I just need to find out more about the different types of glass. 

Thanks for everyones input.
