Hey guys - thanks for your quick responses!
Basically I am just using processwire as a management tool for some help/tutorials on a particular area of my website and am using simple API calls to search and display the page content within my own website/framework.
I have dev and live versions of my website but would like to just have a single instance of processwire sitting on my live server so I don't need to duplicate content between 2 installs etc.
I hope this makes things a little more clear... the 'Pages Web Service' module may well be exactly what I need, I will check it out over the next day or 2, but any other advice or help is very much appreciated.
Thanks again,
DH
