RED can kill GRE tunnels over the net. Depends on the protocol they 
carry. If it is all TCP, you see a lot of slowstart. Of course if their 
path is free of congestion, then no RED.

Plus there is a lot of configuration for GRE, and most platforms come 
with 'managed' tunneling like IPsec, SSLvpn, PPTP.
