And I can see the appeal of the museum direction . . .
I'm not too sure how we would qualify as a museum, and legally novel arguments will usually be a hard sell. What I like about the Vancouver Free-Net situation is that they are an internet based organization which took its case to court ... and won. That makes for a very strong precedent. Their application was based on "other charitable purposes", not education.
The reason it was filed under "other charitable purposes" was because Free-Net was accepted on the grounds of acting as an electronic community (as well as electronic library). Specifically 2 of the 3 judges accepted that provision of access into the electronic highway was a charitable purpose. I think "advancement of education" would be a much better fit. I called up the Charities Directorate at the CRA and they agreed (although to be fair I don't how much I would rely on that).
