Hello,
I definitely agree with that.
A daemon would solve all the authentication and connection persistence issues. 
But the problem is that all accesses to the database that I'm using *must* go 
through a vendor specific API which is only available as a COM library.
This explains the choice of Apache/win32 and Win32::OLE.

In face of the potential problems, I will reconsider writing a RPC::PlServer 
daemon that uses Win32::OLE to access the database.

Thanks for the suggestion.
