Interesting.  I've seen 'CustomString' in the query string, as well as
'ClientVersion', but haven't noticed anything in the data other than
XML.  Haven't looked closely enough yet, I guess.  Thanks for the
recommendation!  Will try it out later today and post results.

How much of ArcXML?  Just GETCLIENTSERVICES, GET_SERVICE_INFO, and
GET_IMAGE at present.  More as needed.

cheers,
Sean
