I don't think so, the sleeping services won't use much (if any) processing 
power) and their memory will be swapped out once physical memory gets filled 
up, but it will improve the initial startup time as those services don't have 
to be loaded and started

That should work as well.

The options I described are still some automated approach, i.e. having 
services started by a super server (inetd) when some client needs them.

Starting on direct usr intervention as you decribed is easier, your script 
only has to initiate the normal startups, using something like sudo.
