Interesting, and thanks for the info and quick response! Do you know if it works from the bottom face of the table? For aesthetic reasons, what I'm hoping to do is have four or eight lasers with a table in the middle arranged in a 3x3 flush with the floor with the power and ME stuff hidden from view underneath it. This of course will only work if the tesseract can pull of the send/receive. I might even recess it into the floor and put a 3x3 seamless glass over it so that there's automated crafting lasers going on under my feet. I'll post some pictures if I get it working when I get a chance to play later tonight.
