homogram attacks: cyrillic and registration guideline

IDN WG had discussed about this IDN-based homogram attacks 3 years ago.
The conclustion is that:   the problem should be solved in registration 
stage,
  not in encoding/protocol level.

So we have now "IDN registration guideline for CJK (han ideographs) 
languages", but that
does not cover cyrillic / greek  ones yet.  IETF  seems to have  no 
plan  to expand  and
publish it.  that is,  "Do it yourself , registries !",

I ask you all  to open this PDF unicode chart   and see  how many 
lowercase cyrllic
alhpabets look exactly the same as  their  latin-alphabet lowercase 
counterparts .

To list some of them, " a  e  i  y  c o s j".
(some of them are not russian,but for eastern europe)

In the uppercase characters, "B H M P" including the above 8 chars.
cyrillicHP.com /ascii HP.com came from the latter category.

please compare the lowercase  "cyrillic iii.com" with  ascii "iii.com"  
. In the address bar,
they may look exactly the same, because cyrillic/ascii fonts are almost 
the same ones
in many OS/GUI  environments.
