Interesting answers thank-you. I actually have posted on the NATCA BBS, with no answers yet...

Ours actually, 'coz we don't separate. We have Class G in which we pass traffic to IFR. Bad weather generates more radio traffic & the odd diversion, but non-availability of distance standards & figuring approach clearances and holding doesn't exist for us. How would you feel about sectors used to the above suddenly being required to provide services down to the ground?
I also would like to hear about the nuts-&-bolts of separating in non-radar Class E.
