AppleScript Remote Event trying to Quit iCal from another computer

Question

I'm trying to write an AppleScript that will allow me to quit iCal on a particular user's account on my iMac from my MacBook, irrespective of if that user is the active user on the iMac.
I did some research and determined that if I enabled Remote Apple Events on the iMac and used the syntax of
on machine "eppc://[username:password]@[machine name]?uid[userID]"
...I should be able to issue the AppleScript command to quit the application.
Here's the weird bit:
If I use this syntax to :
tell application "Address Book" of machine "eppc://[user:password}@i[machinename]/?uid=[uid#]" to quit
... then that works, for Address Book. However, if I copy and paste the same line, and change Address Book to iCal, it gives me "Unable to Authenticate User" as the error and it won't compile.
Strange strange strange...
[By the way, I didn't find an AppleScript forum... is there one? is there a better place to ask this question?]

Answer 1

Did you ever get an answer to this question? I have the same problem on one of several Macs in my office.
This causes a User Authentication error even though the IP address, the user name, and password are correct:
set remoteMac to "eppc://username:password@ipaddress"
using terms from application "Finder"
tell application "Finder" of machine remoteMac
activate
end tell
end using terms from
However, this works fine using the same IP address, user name, and password.
set remoteMac to "eppc://username:password@ipaddress"
using terms from application "Transmit"
tell application "Transmit" of machine remoteMac
activate
end tell
end using terms from
