On the other hand, this feature is very convenient sometimes - user has 
network disk, and he want to open a database on that server. With 
automatic redirection enabled this works fine.

I don't suggest to retain WNet for this feature. In fact automatic 
network redirection is not protocol-related feature, it is OS-related. 
In Unix we redirect NFS mounts, in windows - SMB mounts. TCP/IP may be 
easily used for this purposes with only one potential problem - when 
NetBIOS and DNS names of server do differ. But this means so badly 
administered network, that I suggest not to take into account such case.

Ideal seems a case when single configuration parameter, something like 
AutomaticNetworkRedirection, affects both NFS and SMB, may be some more 
file sharing protocols in other OS's, up to being able to have plugins, 
implementing redirection for, for example, SAMBA on linux. In case when 
AutomaticNetworkRedirection is set to false, remote databases should be 
opened with exclusive lock.
