And here's a version that actually works: You'll need to change the
owserver host (kuro2) and port number (9999) but it displays the
directory entries for root. I'll use this as a basis for a new ownet
python module that provides the same object interface as the current
ow module but only knows how to communicate with an owserver and
doesn't depend on the rest of the core libraries. Once done, it should
run on any platform supported by Python...
