Hi bill,

Thanks for the input.  This prootocol reminds me a bit of OSC, which I've
used before for passing control data for audio applications over networks.

I've found a 'basic' tutorial online that gets one started writing a
'hello world' kind of program with a SOAP server and client, but the
tutorial has problems, the code seems to malfunction.  I'm going to paste
in the files as I found them online, perhaps someone can help me to figure
out what is going wrong.

by the way, the tutorial I'm referring to is at the following URL:
http://evolt.org/article/The_PEAR_SOAP_Implementation/21/49993/index.html

The tutorial says that if I call the client file from my browser, I should
get 'hello world' to show up.  This doesn't happen.  I get some strange
error messages instead, especially after adding the error tracking code
that you suggested (Thanks for that, by the way!).

Here's the errors I get, printed as requested from the client file below:
(apologies for the crappy linebreaks and tabbing)

Printed return from client file:
