What little research I've done suggesst Bluetooth is not very good over
any distance at all. Makes me wonder how good it'd work running these
Bluetooth speakers etc. outside on the patio with pc upstairs on
opposite side of house or in basement recroom etc.

Bluetooth was only ever conceived as a short distance system. The
standard recognises different classes, which represent different
transmit powers. Class 1 can give up to 100 metres range, but only
under good line-of-sight conditions, and aren't common. Wikipedia
suggests (and I believe it) that most devices are class 2, which
equates to a range of about 10 metres, again under good line-of-sight
conditions. Real life ranges will in most circumstances be less.

So you shouldn't expect Bluetooth to work in the circumstances you
describe above.
