"The key point here, though, is that very mention of other
technologies. According to Mainsoft, Microsoft has used MainWin
with Internet Explorer already, bring the browser to Solaris and
HP/UX back in 1997. Extending that is really no big deal and barely
worth mentioning, but the provision in the new contract for .NET
versions of Office is. The only snag is that Mainsoft clearly
can't... well... mention it."
"Linux gets just one mention in Mainsoft's release - not in
connection to Microsoft's latest contract, but the company does
describe MainWin as a "Windows platform for Unix systems, including
Linux."
"Being about to do Office for Linux, doesn't mean to say it'll
happen. But the Mainsoft confirmation of Microsoft's use of its
technology for IE, does make a move toward the Linux world more
likely."
