Unless you use a few of these

I know the G3 iMacs have a bus per port (Wish my PC had that... it'd
be a bit easier on the drain when I use some more power-hungry
preiphials... or ones that just crash the bus)
You also have to take into account that if you use a multimedia
keyboard... you're going to loose 4 devices, one for the keyboard, one
for the multimedia half, one for a usb composite device... and one for
the hub that connects them all internally. (So stick to your
dirt-cheap $2 USB keyboards, and get some nifty hubs)
Another consideration, if you do such a thing: Power... you'll need
alot of powered hubs for that.
