In my opinion kannel-bearerbox should recommend (but not depend on) 
kannel-smsbox and suggest kannel-wapbox - exactly to allow running from 
separate machines.

I don't know if Kannel not already spits out sensible errors in log 
messages, but if not then yes, that's a good suggestion to pass 
upstream.
