Gross left and right aren't particularly important to most species, though the chirality of some molecules determines their biological function. Faced with a coronal plane image of a human or a spider, I could probably work out that it was vaguely bilaterally symmetric and had a preferred orientation with respect to gravity. Given three projections and a scale (the hydrogen 21 cm line is likely to be a universal standard of length and time) I could make a fullsize model of it. So it's entirely possible for any life form that can control an electromagnetic technology, to initiate meaningful conversations with another.

I think that we need to find some aliens before we can learn how to effectively communicate with them.  Which would mean hopping in a space craft to start scouring far off solar systems for signs of life.

In order to do that effectively we would need to go light speed or beyond.  Thinking about how to make cheaper and faster space craft.  (warp drives and stuff like that would be completely necessary)

Intelligence seems to be the realization of not knowing enough, then start asking questions. If the universe works by emergences, meaning 'jumps' that you don't really can back track to their constituents behavior before this 'emergence', then intelligence should be able to pop up everywhere I think.

We recognise intelligence in another animal by its ability to surprise us. It is the antonym of mechanism. So we should be looking for the mechanistically improbable- like the "WOW signal". The difficulty is recognising the difference between a surprising signal and random noise.
