I ask because in four years with my MacBook using it for a whole range of stuff (including development, multimedia, general admin,, and installing whole loads of software I've bought in bundle sales) I've honestly never seen this problem.
I'm not saying it can't happen but from my experience you'd really have to be going for it to build up that sort of accumulation of stuff in just six months.
Not now, but I used OS X for a few months. Various programs installed some daemons, including VMWare (I see no reason why) Little Snitch (okay, that one's justified) and various other things I can't remember right now...
