Yes, definitely. Twisted has code for doing daemonization/pidfile management 
that is much more flexible than xend's current approach. I looked into 
refactoring it to use that as well as adding support for Twisted's 
remote-object protocol, but I kept finding things about xend's architecture I 
wanted to change, so I gave up temporarily :) I will probably revisit this 
after finishing my current project, which just talks to xend via its HTTP 
protocol. Basically what needs to be done is to remove entirely the code in 
SrvDaemon that starts things up, and use 'twistd' to start it instead.
