We had to do something similar for a "secure-ish" network.  We're not
using Rancid per-se, but a homegrown tool that is conceptually similar
enough that also uses clogin and RCS.  

In IOS, you can create users that can only run 1 command automatically.
So for example we have:

username ios-copyrun privilege 15 password 7 xxxxxxxx
username ios-copyrun autocommand copy running-config running-config.save

Now, when you ssh "ios-copyrun@device" (say, via clogin) you get the
config saved to a file.  Now, come back with a priv 5 user to scp the
file off the device.

With building blocks like this you can hack up something that is slightly
better than throwing priv 15 all over creation.  I don't know what Rancid
does, but maybe you could script something up.  

Perhaps someday when IOS incorporates security technologies from the 1990's 
like 'sudo', life would be easier.
