That's what I was afraid of, but thanks anyway.  This is my first experience with One-Wire and probably my last.  I looked at the 64 bit serial numbers and decided to use a separate pin for each device.  Much simpler and saves RAM.

I've also discovered that the OW**** instructions eat ram hugely.  I ended up writing subroutines for every OWinstruction I use and using an IF-THEN-ELSE to send the instruction to the proper device.  
doOWRESET:
IF Direction = 0 THEN
   OWRESET RC.0
ELSE
   OWRESET RC.1
ENDIF
RETURN

That lets you handle two devices and saves a ton of ram, but it's clumsy.  But, considering the price, I'm not complaining.
