The United Nations are discussing whether the U.S.A. can still be 
allowed to have ICANN and dominate the Internet. So many countries 
would like to say 'N(y)et!' to so many parties that would like to have 
their own domain names and publish things not 150% compliant to their 
so-called governments' point of view. Is the day near that we shall 
have to ask permission to switch on a computer? Should I wish to be 
much elder than Herb?

I can understand that it's risky to have some \special in the DVI like 
"`<some command> <../../some file>", but in passively including some 
graphics file 'from above' I can't see so much of a risk -- except on 
MS Windows (is MS more descriptive than Mighty Sh..?). Wouldn't Earth 
be a fine place to live with two letters less in the alphabet?

dvips.pdf and dvips.info are still old, only 'man dvips' shows the 
right information.

/usr/local/teTeX/share/texmf.local/dvips/config/config.ps still has the 
well-known (?) entry:

	% Last resort bitmap sizes.
	R 300 600

and additionally

	% z1 is "secure", i.e., inhibits execution of `shell commands` in
	% \specials.  Dvips allows this by default.

Would it work 'insecure' with R0? Or z0? Neither works, not even 'R 0'.

Markus, your eMail arrives with some secure offset. Do you need the 
names of some NTP servers? (NTP = Network Time Protocol)

Mit friedvollen Grüßen
