That, in my view, is an unreasonable expectation, and requires software 
which is being used because it is excellent at doing one thing to be a 
jack of all trades.

The limitations tend to be commercial, security, and broad definition 
accessibility, i.e. the plugin may not be available because it not 
available for the user's platform, is too expensive, is considered an 
unacceptable security risk, requires too many machine or network 
resources, requires reflashing 1000s of kiosks scattered around the 
country, requires updates to a set top box whose manufactures no longer 
exists or has abandoned support, etc.

public-html has been dropped as my posting to it will not succeed or 
will be excessively delayed by moderation.  Cross-posting works on 
unmoderated usenet newsgroups, but public mailing lists are generally at 
least minimally moderated (subscribers only).

RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
