some combinations are problemaic, but it's tricky and there's a lot to do...

we don't have quality of service. it's not even in the current spec.

what you are seeing sounds more like a bug... if there is a single
piconet, no scans are being started, then we should get good
consistent throughput.

other services have to behave too. since there isn't a way to tell
services individually to role switch, the best we can do is put this
in hcid.conf. (I think you already did this)

lm accept,master;
lp hold,sniff,park;

iirc, it's outbound connections from your computer that briefly create
a scatternet until the role switch happens. there's no way around it.

I've noticed gstreamer does take too much cpu, but everything else
behaves. I've been testing this stuff on a 400mhz gumstix... I like to
see it scale down too.
