We have 2 span sessions going to 4 destinations as follows:

#sho mon
Session 1
---------
Type                   : Local Session
Source Ports           :
     TX Only            : Gi7/1
Destination Ports      : Gi9/17,Gi9/41


Session 2
---------
Type                   : Local Session
Source Ports           :
     RX Only            : Gi7/1
Destination Ports      : Gi9/16,Gi9/40

with barely any effect on CPU.  We got hit by CSCsb21148 though - we had 
an ACL on one of the source GigaE ports.  So you may lose data but it 
won't affect your CPU :-)
