Cordless phones are fun anyway, I recently built a remote power controller for use with an analogue Siemens Megaset base station. (The base station in the ground floor, next to my father's desk, is powered all the time, "picking up" the handset energises a relay that switches on mains for our DSL modem and ethernet hub. Handset is next to my desktop PeeCee in the first floor and powered only when my desktop computer is on. The controller of course also has a local switch wired in parallel, for when my father wants to go online.) I'd be very interested in such an arrangement, but I have the suspicion that there will be no convenient location in the handset's circuitry to interface a phone line to. For the DECT system anyway, there are things called "cordless phone sockets"; they aren't really cordless as they need a wall wart, but they are learned to the base station like a new handset is and present themselves to a phone/fax/modem/whatever like a phone line. Would love to get my hands on one of those one time. I see it's hard to make do without permanent cabling, but the ports shouldn't be such a problem. You could just run two links into each room where you have machines (to a wall socket), then use temporary cables to connect just the machines on which you are working at the moment (either two in one room, or one in one room, one in another - therefore two links).
