This surprises me somewhat.  The config variant you use to configure the 
IPSEC stuff on your end should be completely transparent to the other
side, as long as the resulting packets match:

 - IKE phase 1 + 2 proposals
 - IKE phase 2 SA  (= with crypto maps: tied to ACL lines)
 - protocol stacking (IP-in-GRE-in-IPSEC?)
