Those are one option (one I don't like BTW).  Actually, I was alluding to
the Harvard Architecture.  But however they choose to do it, they'll
either have to fix it or suffer the financial consequences.  What they
*can't* do is put the genie back into the bottle - that particular genie
is getting gray hairs now!

Also, that Cisco must fix was not the point of my argument.  I was trying
to point out that Jaosn's basic premise that this was a grossly negligent
act by Cisco is pure fiction.
