Everything people have been saying about PNG and other modern file
formats is true (AFAIK), but we have hundreds of pieces of IDL code that
write GIF's, and support a library that has hundreds more. some of them
ar eused in server mode to produce hundred of iamges a day that go to
our Web sites. Simply doing the global replaces and testing the
resulting PNG's would cost us a lot more than $475, if that's the price
for a US governemnt institution (we usually pay higher prices). That of
course, doesn't count the incoveneince for users whose Web browsers can
handle animated GIFs, but not animated something else.

I'm expecting a fax from Unisys RSN; we submitted the questionnaire
a couple of days ago.
