NO! No problem at all. In fact, apologies if I have maybe not  
responded on the point - I have no time to follow closely, mostly  
posting whenever I see a mail that triggers a thought.

But the general question remains: Does any definition exist that  
would allow me to distinguish SOA from <put any distributed object  
technology here>? Especially if we consider that SOA in a sense  
enforces some DO design practices while Corba et al. do not, but that  
it does not build upon a conceptually different architecture.

Another way to ask: is there anything about SOA that makes it  
architecturally different from old-fashioned DO technologies?

Sure, you have language independence, free choice of transport  
mechanism,.. but this does not make SOA a distinguishable software  
architectural style (which the name[1] implies, IMHO).

And if it is not....then  it is just as good as the old stuff, isn't it?
