I went through the daemon script and I'm not able to understand what exactly you want.. Perhaps you can post your edits to the script here and I'll try to merge them in?

Well, for starters run it without args as a normal user, and then run, say, network without args as a normal user.

In fact, if you do that in a loop:
for x in /etc/rc.d/*; do $x; done

The only one which fails is transmission.

Many of our other daemons require root to run, but none check for it. Further more, transmissiond can be run as a user just fine.

also this needs to be assigned to someone else. Oh it seems Roman is the transmission maintainer now :)
