Because, we all know that we have issues, say prescription writer or II folders, II period. Now, we can decide to do workarounds or not upgrade.
If AC were to host AC, we would be at the mercy of how each build came out. I could just see users scrambling for support when AC had a bug. Maybe it would be easier for them to fix the bug right there and not have to put out a new edition. But, I thought everyone wanted their own program and not ASP version.
