Sorry, No - not up to even thinking about that stage. 

I just remember that when ian put our database on one of Horsts Servers, which 
I think was located in germany somewhere, I was amazed how well it ran.

I guess it depends on the size of the query and what you cache on the local 
machine. I tend to pull only small bits of info from the backend at any one 
time - I adopted a "just in time" approach - plus linked to a timer - so that 
there is not continual polling on the backend - only does the call once the 
user pauses + if dealing with lookup type data - its pulled from a local 
cache. 

As you know Sebastian, I'm not a real good programmer and certainly have no 
technical knowledge about this stuff.
