solder paste for SMD is just solder "dust" and flux mixed to a paste. it  
must be soldered (melted) to work, and it would bead up with no copper  
under it.

There is conductive epoxy, and various conductive paints, some of which  
can be soldered to, but i believe it will be a number of years until it  
can be used.

For now i'll concentrate on EDM, as this is most promising.
