I'm not familiar with the actual mechanics of the slave itself - 
I'd look for a documented KDE example with C++ code and work 
from that if possible.

This may be way off target, but it seems you should be able to 
derive from SlaveBase (or TCPSlaveBase) and instantiate that 
object, and then use Connection and SlaveInterface to 
communicate with it. It should work within a single program or 
between programs.

The problem with panel applets is that you need to create a 
libtool lib for the loading mechanism, which can't be done (at 
least not easily) from Python. I don't think that's necessary 
with IOSlaves, but I'm really not familiar with how the 
on-demand loading mechanism and mgmt operate, or even the 
details of communicating. 

It appears all the necessary machinery should be available in 
PyKDE (unless there's a requirement for lib loading similar to 
panel applets). The only other qualification on that is that 
some of the socket related stuff in KDE isn't implemented, but I 
don't think that applies here.

Can you expand more on the shared library you mentioned creating? 
If there is a C++ lib req'd, I might have some ideas in that 
direction given more particulars.
