Great suggestion RML!
But those old houses have lath and plaster walls, covered with who knows how many layers of paper from years of remodeling. Using the duct work is a possibility, and many of the old Seattle homes do have central gas heat, with ducting everywhere.
Following a chimney might be a great choice too, as many of those old homes had (originally) a wood furnace in the basement, and later an oil furnace to replace it. The chimney may be there but buried after getting abandoned in favor of the gas heating systems.
Sometimes you can even just find a discreet place to drill through a floorboard, depending what ceiling access the basement has, (Suspended ceilings may not be the epitome of craftsmanship, for instance, but you could put anything up there and still be able to get at it easily, as many teenagers learn.
) and of course, what the floorboards are made of. Depending how the wireless transmitters hook up into the system, it might even be a good idea to put the transmitter upstairs and run RCA cable or whatever to it.
Anyway, what the walls are covered in is less of an issue, (The thing with plaster and lath is you want to score carefully around any holes you want to drill and use sharp tools, (it could be brittle or loose in there) you dont' want the lath flapping around or plaster to prefer to crumble.
) What's really important is the kind of framing behind it: you don't want to have to drill through solid sills, but some construction actually allows a pretty easy sneaking around it.)
Easier in any case to not bother with the walls or slills if you don't have to. But if the wiring or plumbing's been upgraded there's a chance there's a straight shot next to pipes or other utilities. Forced hot air and the returns for such are sometimes retrofits (with little gaps where they fit up the ductwork, covered by the grills or registers, )and you might be able to sneak a wire past the sheetmetal of the duct or even just run the wire through the duct: drill a hole in the galvy right below, and either put a string up in there to just grab and bring upstairs, or push through a straightened coathanger to attach a string to and fish it down. It all tends to be specific to the house, in the details, but there are doable options there.
Also if there's any call to upgrade any old outlets, there's no reason you can't have the electrician fish any other kind of wire alongside the Romex, set it up all nice in a wall plate. Which is what we did in a house renovation I worked on, we upgraded a lot of the wiring and put in sometimes four-gang plugs, coaxial cable, and Ethernet (and a piece of string for anything else that might come up later) all in the same panels. All very cool for an old Italianate house with a lot of students living there. It was before wireless was a thing, but the whole house didn't need it. Everything ran from all over the house, down into the basement, and back up up into a cabinet area for an Ethernet hub (and a well-labeled diagram of the whole thing.
Not to mention redundantly-labeled and color coded wires. Capacity to wire the place for central sound was also there, but left for later. For that I made do with certain improvisations like I'd just mentioned. As I recall, I ran the speaker wire under the floors to where the big ol' speakers would go, and temporarily set things up so that we could put other speakers in the windows so that the same music could be heard outside if there was an event going on.
This was always intended to be a temporary measure since the plan was to obtain outdoor speakers and later put a ,pre dance-friendly floor in, but it's a lot better than tripping on wires.
Anyway, biggest point there is if there's any old wiring needing replacing anyway, nothing says the job gets much bigger if you fish other wires at the same time.
But sometimes there's a professional way and sometimes there's an unobtrusive kludge. Air ducts, if present, are *designed* to go from the basement up to near anywhere in the house. No reason you can't put a wire in there along with, generally. (And would you expect any less from da Ratlady.
