New Post: [noob] Can I use SPServices from outside the SP site ?

All is in the title, but let's be more specific.

After reading the first steps documentation, I realize that the page using the SPservices is hosted within the SP site.
But I'd want to read the content of a SP list from an external site (different domain, non SP site, SQL server and Colfusion 8). Even noobish as I am, I forecast big troubles with credentials.

So I'm just wondering ... if I'm in the right place ;)
Ad if, by luck I am ... could anyone lead me to appropriate example or documentation ?

Thanks for your time, sry for this level 0 question ...
