You are definitely right, but even even I have problems understanding the
complications of Bidi. And specially since ZWNJ and ZWJ are involved in
the game (which are rare in Arabic), honestly, I don't think Arabeyes
people will be able to help much.

OK, Homework 1:
Study the Unicode 3.0 section on Arabic thoroughly. Check Unicode 3.1 and
3.2 to see the changes that has been made to it. Try to understand *every*
detail, specially the notion of character sequence <ZWNJ, ZWJ, ZWNJ>.
Suggest re-wordings to make these more clear. Best comments will be
collected and sent to Unicode editors to be incorporated in Unicode 4.0.
Study the Unicode Bidirectional Algorithm. Think about possible problems
that may rise in interactions between Bidi and Joining, specially ZWNJ and
ZWJ, and Arabic text in overridden Left-to-Right mode.

Please do so. CC me in case of any difficulties. I have just met some of
the Unicode officers, and may be able to provide some help.

We can try that, but being a member of Bidi doesn't help much if you can't
access the L2/UTC document repository which is password-protected and only
for members. You will see people discussing some number referring to a
document, and get into more confusions.

Sure. But the sad point is that Behdad is changing his opinion everyday ;)
BTW, just out of curiosity, how many people here are members of the
"unicode at unicode dot org" mailing list?
