Gunnar Grimnes recently blogged about his happy moments with the combination of gnowsis 0.9 and python.

the code looks something like that here:
#!/usr/bin/env python
from xmlrpclib import ServerProxy
server=ServerProxy("http://127.0.0.1:9993");
#print server.listMethods()
print getattr(server,"gnowsis-server_dataaccess.querySelect")("gunnar","fulltext")

but read Gunnars original words for full bliss.
