Are you talking about user-mode DAT/DAPL or kernel mode.
For user-mode, the DAT registry mechanism and the dynamic
loading of shared libraries seems to work OK and I 
see no need to change it.

For kernel-mode the method for discovering RDMA (DAPL) providers, 
or having them register with an RDMA mid-layer should be something 
that fits in better with Linux. 

my 2 cents,
