Sorry that you are still having problems getting a system chosen. You have given a budget now, so that should help others get you set out with a shopping list that will meet your needs.

Bridged mono is something completely different (taking 2 channel amplifier and combining channels to drive one speaker with more power) - don't worry about that.
Yes, a whole house audio system could work as long as you have enough amplifier channels - one for each speaker. That Dayton Audio MA1240a Multi-Zone 12 Channel Amplifier - $495
would be able to drive 12 separate speakers. You could use local volume controls which will adjust the volume of two speakers at the same time.
To make the system mono, you would only need a stereo to mono converter installed between the source (your PC) and the amplifier input - something like this:
Monacor SMC-1 Stereo to Mono Audio Converter - RCA Input and Output - $25
I still think these Dayton indoor / outdoor speakers would do the job for low level background music at a reasonable price - if you don't need the 70V capable ones they are cheaper:
Dayton Audio IO655W 6-1/2" 2-Way Indoor/Outdoor Speaker Pair White 8 Ohm only
The other way you could go is to use "impedance matching volume controls" - you could use one pair of amplifier outputs and one pair of speaker wires to connect "up to 8 pairs of speakers each" - the volume controls are more expensive but you wouldn't need as many amplifier channels (maybe only one pair per floor) - that amplifier above would be able to run 6 zones and you would have a volume control for each pair of speakers:
Niles VCS100K Volume Control Kit
- Connect up to 8 pairs of 8-ohm speakers to a single stereo amplifier (requires 1 volume control per speaker pair)
Amplifier $495, Speakers 6 x $80/pr
= $480, Volume controls 6 x $60 = $360, Wire + mono converter + misc = $200, about $1500

Like wiring a 70v system to a bunch of in-wall volume controls? I could daisy chain the volume controls, and then just run up to speakers...would this give me multiple zone control?
It wouldn't be that expensive if you just used four of these small amplifiers - one for each zone - they are only $130 each. You would probably need to locate them all together so you could feed all of them from your PC source but they have a volume control. I don't know if you can use volume controls for a 70V system.
The big advantage of a 70V system is the wires - for this 4 zone system you would only need 4 speaker wires - one to each amplifier connected to all the speakers for that zone. The other system would have a separate wire for each speaker connected to the amplifier.
