Ok. Thanks, I didn't think of that. This should probably help quite a bit.

Yeah I am currently thinking of the best way todo this. I guess I now reach
another point. Does anyone know how to make External Methods persitent, or
would I have to store cached information on the filesystem. Does ZCache work
for External Methods, are there any plans todo this? I don't mind writing
code for ZCache todo this if the current framework easily allows this.

Thanks,
