As far as I know that’s not possible.

As long as they have Designer and can connect to the repository they can get to the source code anyhow. A direct connection to the database will let you look at source code also even though it’s a bit challenging. I wrote a utility to export all dataflows from a repository to individual files. So I know reverse engineering can be done without Designer.
Encrypting the ATL file won’t do you much good.

If you really don’t want people to change your code or be able to roll back… just create an export and store that ATL file into a TrueCrypt volume or something.
But no you cannot actively distribute ATL files as a product and protect it.
Having said that, I wouldn’t buy “external” ATL’s (as products) anyway none of them will contain any functionality not offered in Data Services - unless you call specific binary components. But then you would sell the components rather than the actual ATL files.
