Thanks for the responses. Yes, I was considering something like gSOAP or
libxml2.

In the meantime I got the permission to write my LS client in Python. So
I hope, I'll find some code to use as a starting point.

Until now I was unable to install my own homr LS for testing. The tail
of ant -f build-xmlls.xml deploy:

    deploy-adminclient:

I don't understand, what produces the error, I followed Maciej's
installation instructions exactly (with the difference that tomcat was
downloaded from apache.org, unpacked and pointed to in ant pre-install
step).

Also I came to this page

http://wiki.perfsonar.net/jra1-wiki/index.php/Lookup_Services

Can I use some of the 3 Lookup Services listed here as a sandbox while
developing the client? Or are they used for production?
