Jamie, Since the server allocates the array, are there any issues for AT
regarding the method I proposed? 99% of the time the array will hold
one accessible. Sometimes the number will be higher but if you only
want one you can just access the first one in the returned array. If
you want all or some of them you'll know how many there are. I'd like
to keep all the array access methods consistent unless there is a reason
not to.
