Cool!

How important are the exact values? I happen to have a large pile of 10k's and 100's here but not any of those particular values. I could parallelize or serialize to get the exact values but that starts to get annoying in terms of the number of resistors.

Either way I could definitely test this arrangement.

Is arrangement you've illustrated a directional thing? In other words, does it only work if the supplier is one spot and the receiver is in the other? Or could it also work in reverse?

I ask because I'm not sure who's who out of each of those three pins we're using.
