The PreEmptive Dotfuscator 3.0 (professional version)
in evaluation mode works for 14 days.

It dotfuscates .exe  and  .dll (common .dll and aspx .dll) .

Dotfuscator scrambles the original code and
it adds new code to the original code.

The resulting dotfuscated file,
in your opinion,
does contain code that "phones to the Dotfuscator home" ?
(expecially about an aspx .dll file, which is always on-line)

And, if yes, what does it communicate ?
