And my secondhand electronics purchases:

I thought I'd better try out the multi-room casting...
Set up the two new CCAs bought for £15 each from Curry's.
Create a new group, clustering the devices together.
Connect the three CCAs to amps in different rooms.
Select the multicast group as renderer in BubbleUPnP and hit play.
After some turning off and on again, I now have music playing in sync in three rooms.
Some dropouts downstairs, maybe due to poor WiFi reception.
Pretty damned impressive... And a damned sight cheaper than Sonos...
