Aren't we reinventing the wheel here?

I mean, if you take a look into the Koo (OpenObject KDE client) client 
repository ( https://code.launchpad.net/openobject-client-kde) you will 
notice that it already may use a statefull protocol to connect to 
OpenERP server: Pyro!

The Koo project already includes a server module (for OpenERP 5.0 
version; 
http://bazaar.launchpad.net/~openobject-client-kde/openobject-client-kde/5.0/files/head%3A/server-modules/pyro/ 
<http://bazaar.launchpad.net/%7Eopenobject-client-kde/openobject-client-kde/5.0/files/head%3A/server-modules/pyro/>) 
that provides that Pyro protocol support. So on the server side the only 
thing left to do is include it on the base server.

Pyro is statefull and fast and does all the hard work for us, as it is a 
object-oriented RPC-like protocol (http://pyro.sourceforge.net/). And 
has been already tested by the KDE client.

Thanks to Pyro, and some other optimizations, the Koo client overall is 
one order of magnitude faster than the GTK client over slow or 
high-latency networks (DSL/Cable).
