I am using "Single-Threaded Apartments".

Yes, I believe so.

But the use of ATL is accidental, not essential. 

I mean, we can use other Windows C++ compiler to make a COM server. 

It just seams natural to use Microsoft because this the one we use most of the time to develop gdal drivers and utilities.

That is something cool too. You can access it from ASP, ASP.Net projects too.
