I think we might have a bit of a terminology issue here. From the operating system's standpoint, web2py is a service. I'm not talking about that. When I say web2py service, I mean things that are strictly linked and (I dare say) actually are *meant* to run under web2py, but are not tightly coupled with the actual actions of the user (see session cleanup, cron tasks specific to the application). As a requirement, web2py services should be able to run under whatever platform and environment web2py is running from, something that is certainly not easily achieveable if this is done as a separate service.
As for Steve's concern, I've just sent a proof-of-concept patch to Massimo which does the above in a way that does not cause any detectable performance degradation for users. As for the last post, I don't see how you can control web2py services from a web2py application ? If you're not root, you have no access to init scripts (and you certainly don't want web2py to run as root). If you're running under mod_wsgi/fastcgi, you can't even control the current running process, much less influence the actual webserver web2py is behind.
