Vår fungerar spore duschar?

"Her u-shadow told her when it was eleven o’clock, which barely gave her enough time for a spore shower in the fourth apartment where she was living. Two of the old shower’s five nozzles weren’t working, and one of the remaining jets smelt funny"

Sporerna beskrivs som "sprutade" från fixturerna:

After the shower had squirted dermal fresher spores over him, he walked through into the vast lounge, bronze sunlight washing warmly across his tingling skin.

Sporerna orsakar:

a slight tingle on the skin

Sporerna kommer ut ur munstyckena vid olika temperaturer, under användarens kontroll:

So he turned the spore temperature down about as low as it would go, and thought of other things.

Sporerna verkar vara torra, snarare än i suspension:

Then there was a shower—none of that modern itchy spore crap that clogged up his hair but a proper hot water and scented gel affair.

Sporerna kan användas i samband med vatten eller på egen hand:

“Good.” He stretched and rolled his shoulders. “Give me a shower,” he told the smartcore. “Start with water; shift to spores when I tell you.” ... After the spores cleaned and dried his skin he dressed in a simple dark purple one-piece suit

Sporerna själva kan vara ett derivat av vaxartade "sporecones" som ses i den andra boken i serien;

They made camp that third day under overhanging branches which dripped an unpleasant waxy sap from their newly budded scarlet sporecones.

Sammanfattningsvis verkar konceptet vara extremt lik "pulverduschen" som ses i filmen Tankflicka , om än med ett aktivt (biologiskt) rengöringsmedel i stället för att bara använda slipande damm.
