    Hi Addy !

    Just wanted you to know that this tip seems to apply to scenarios where a custom web service is to be installed on the SPS machine as well. I’ve seen this mentioned on Google groups and here, and it actually worked for us, but I still need a better way since messing with the site-wide trust level is something I would like to avoid. Perhaps there is a way to change the existing trust levels to be more specifically generous towards this web service in particular (as it is when using the SPS object model from a web part)? I’ll check this out later (when a presentation is NOT imminent).
