I wondered what people's feelings/experiences were with respect to 
completely disabling STP where appropriate?

I have 100% control over topology and some PtP dotq trunk links, I 
thought of placing 'spanning-tree bpdufilter enable' rather than 
'portfast trunk' on these ports. I have no need to to send or receive 
STP BPDUs on these ports, even though the underlying technology is 
Ethernet. Hosts are a mixture of L3 switches and routers, but 
configuration should limit the extent of the broadcast domains in 
question to exist only on the PtP link.

Cheers,

David.
