sure, but as an edge solution (the original question), it works.   
still, I wouldn't let customers control this configuration, if they  
just don't configure it (properly) and form an loop that mightn't be  
shut down properly.

I'm told you can also tunnel the etherchannel using dot1qtunnel to  
give a customer (or rather, your gear at the customer site) an end-to- 
end 2g/whatever service through your network. I've not deployed that,  
though I'm informed it has been done as a semi-regular offering  
somewhere.  I wonder how brittle that is.
