RE: Topologies and attendance
Oh, some very interesting options...
a) USB power ports on UPAMD adapter - sounds good to me , but it may be made as "normal" UPAMD port, and special cable-converter (with built-in logic to communicate with UPAMD adapter, to send messages as "please set 5 V, with limit xx, for as long as you can")
b) such cable-converter could be also made e.g. for my tablet - built-in logic should only send other parameters to UPAMD adapter. Maybe some company would manufacture cable-converters with some method of manually setting parameters as voltage and amperage :)
c) and most important, what you drew on "expansion box" - more than one concurrent power input. How would such possibility add to cost of adapter/expansion box?
I think we should vote about "more than one concurrent power input" configuration - allow or disallow (support or not support) such configuration.
d) also "expansion box", UPAMD device after UPAMD device. It suggest that "expansion box" should steer UPAMD adapter after any plugged-in (to expansion box) device change parameters. It requires more work on communication protocol.
I think this is another topic for vote - existence of 'active expansion box', i.e. not simply split power from one socket to more sockets, but also for e.g. voltage conversion in it.

UPAMD,
Attached is the topology drawing I promised to send out to stimulate ideas on the things the UPAMD power distribution system can accomplish. These are just potential thoughts. Feel free to expand and share.
I did not realize that Austin was not on the call and I failed to capture the attendance. If you were in attendance please send me a quick email to that effect.
Respectfully;
