I don't think that it is OK to say "you have to have IE or netscape to use
SSL". Apart from anything else, it just isn't true. (Similarly,
http://www.mbta.com excludes browsers other than those two on the grounds
that CSS and javascript are required. Even if those browsers have CS and
Javascript deactivated. And it excludes Opera 5.0, which has fine CSS and
Javascript support).

On the other hand, I think SSL is a requirement that it is reasonable to make
on a browser - it is now widely available (Lynx, iCab, IE, Netscape, Opera
all provide it and I believe there are others as well).

  comment on 'Guideline 4: Compatibility.'
  how are we handling companies that have made a concious effort to set a
  minimum standard for browser compatibiltiy?  these decisions are normally
  driven by cost and security - especially where secure socket layer is used
  (SSL).  do we have an alternate method for people to access information?  do
  we need to address security here and state that there may be overidding
  reasons and justifications where a call center may not be avaialble to help

  overall my i think this is a great step forward and need to look at teh cost
  impact and help those people who do not have the funds nor technical means
  available to satisfy each line item in the quideline.
