Hi Andi,

ASP.NET is using OLEDB, as well, and in my experiences this does not add 
to much penalty to communicating with MSSQL (however obviously more 
exhaustive performance tests are required). However I am wondering 
whether the OLEDB way would still work on non-Windows PHP versions? If 
not: Having two compatible, but internally completely different MSSQL 
extensions for win32 and non-win32 sounds dangerous to me.

As far as I know, and I might be wrong, ASP.NET uses a managed runtime .NET
interface which does not use COM (It's the actual TDS protocol implemented
in managed code). COM is viewed as poor way to run such interfaces both for
performance reasons and resource reference counting resources.
