when to use canonical->non-canonical conversion

Guys,

this is to summarize and confirm the usage of canonical to non-canonical
mac address conversion:

Are there other places where one might need to to the conversion other
than the following scenarios:

1. dlsw icanreach
-----
{ethernet}-----RouterA-----{cloud}....

ethernetA has device with mac address 1.1.1 (non-canonical=0080.0080.0080)

we want to use icanreach on RouterA for this mac address, but we use
non-canonical here:

dlsw icanreach mac-addr 0080.0080.0080

2. dlsw remote-peer xxxx dest-mac:
-----

{ethernetA/tokenringA}---RouterA---{cloud}---RouterB---{ethernetB}

"ethernetB" has device with mac address 1.1.1

thus on RouterA:

dlsw remote-peer 0 tcp <RouterB> dest-mac 0080.0080.0080

--side question for #2, does the above change if the source LAN is
ethernetA instead of tokenringA?

{
if the above reasoning is correct, then the answer in
KarlSolie, Enchilda, pp1168:
Section XI: Question1 is incorrect as per:
http://www.ciscopress.com/content/images/1587200023/downloads/Skylabs-enchilada.pdf

where he hasn't changed the canonical -> non-canonical format.

}

3. source-bridge input-address-list
----------

{tokenring}----{to0/0}RouterA(e0/0)------{ethernet}

ethernet has a 1.1.1 mac address device

on RouterA t0/0
source-bridge input-address-list 700

access-l 700 deny 0080.0080.0080 FFFF.FFFF.FFFF <----
access-l ......

4. bridge-group input-address-list
----------

same scenario as 3, but mac address 1.1.1 is on TokenRing

RouterA e0/0

bridge-group input-address-list 700

access-l 700 deny 0080.0080.0080 FFFF.FFFF.FFFF <----
access-l ......

any other scenarios??
