Hi again Ron.

Nice to know that there's a large-scale organisation like that using 
Caché - you guys will carry considerable clout for getting them to 
change things if needed :)

I must confess I didn't know there was an XML interface. However, I 
suspect that it may be a reasonable way to go given a fast enough link 
between the client and server machines, and fast enough client and 
server hardware. Of course I have no quantifiable metrics for this, but 
now you've mentioned this interface I'll probably take a look at it.

Glad to have been of help :)

I haven't yet asked them about their specs directly. I've dropped a few 
hints in support emails but they've either missed them or ignored them - 
hopefully not the latter as that would indicate that they don't want to 
give them up. Still, that's nothing but guesswork and I just hadn't got 
around to asking them properly yet - so many other things on the go at 
the moment. However if there are two clients asking for the same thing, 
it would hopefully mean they'd be willing to cooperate; I can't really 
see why they wouldn't want us to add to the range of interfaces to Caché.
