Well ... Michael works in a market where dotLRN might well be deployed as the base for an intranet (or be used to build such a thing), so they wouldn't necessarily have a traffic load that Win32+OACS 4 couldn't handle.
And if a company accepted OACS 4.5 and liked what they were getting, and were faced with performance and reliability issues, they might be more open to a Unix-based upgrade than they would be when Michael first sticks his foot through the barely-opened door to make his pitch.
I'm sure there are others in the same boat. Getting in the door will be much easier with a Windows-based solution, many of the clients won't be overwhelmingly large in terms of heavy use, and once they're sold and trusting the team and technology, they may trust further technical recommendations. At least the odds would be a lot higher than when in the initial sales situation.
