I'll spend the rest of today trying to get my head around the code/debug if 
I can spot a problem I'll feed it back if not it will have to go on my 
revisit list as I'm pretty short for time.

No, our code via php bindings

sadly omega will not do what we need, however, I was thinking whilst 
looking at the server code that I could probably write a light weight 
server that implemented the required logic in 1 or 2 days. It's not the 
ideal solution but it may well provide a way forward.  I think we have plan 
B for Friday and the weekend.

Again both of you many thanks.
