Slashdot | Submitting Federal Proposals Requires Windows:
"The US federal government is requiring that proposals for grants etc be submitted using a common system at http://grants.gov/. That's a good idea, except that effectively, you must use Windows and Explorer. See To operate PureEdge Viewer, your computer must meet the following system requirements: Windows 98, ME, NT 4.0, 2000, XP... PureEdge on Grants.gov will not run within the Firefox browser. They do have a Citrix substitute for non-Windows users. However the site goes on to say "Note that a limited amount of users can access the Citrix Server at any one time... Finally, you will find the best time to work and submit an application via Citrix is during off-peak hours, usually between 10 p.m. and 10 a.m., EST. Finally, if your organization has more than 10 non-Windows users, they want you to add a dedicated Windows box to handle the traffic. For National Science Foundation clients, this is a big step backwards. NSF has had an excellent online system, http://fastlane.nsf.gov/ for years. Fastlane has no bias towards MS. However, by federal edict, NSF people must also use grants.gov."
