Right. The problem is that Calendar needs to be able to construct a 
complex message (especially complex because of the messy state of 
support for flavors of iCalendar/vCalendar formats) and tell a MUA to 
send it from a specific address. I expect the same is true for Aperture. 
There's no way to construct a mailto: for that, so the solution is to 
use the particular OSA interface that Mail offers. Even if another MUA 
were to provide an identical interface there's no mechanism in MacOS to 
make other programs use it.
