 ah - you have a different design architecture, okay.

 well, i feel confident that you will be able to come up with a
 methodology that will enable you to pass RPC traffic over to a samba 3
 server that fits with the samba 4 design architecture.

 and, also, ultimately and probably just for fun or maybe even a
 practical purpose, to pass traffic back the other way (!) namely to
 allow administrators to continue at some point, maybe for legacy
 purposes, a samba 3 smbd, whilst at the same time upgrading to samba 4
 NT domain compatible services.

 circumstances under which i can genuinely see a need for this would be
 because samba 3 supports oh i dunno windows 95 clients better or
 windows 3.1 clients better or something ridiculous, and samba 4, being
 the less mature project, hasn't had the benefit of fifteen years of
 gribbly-bit real-world exposure.

 i am sure that the people who choose to assist you with this endeavour
 will benefit from your advice and guidance.

 my only sincere hope is that there be a common API that allows present
 and future versions of smbd (tng, xad, 3, 4, even cliffs god-help-us) 
 and other SMB client/server projects (most notably current open source
 projects Wine and ReactOS) to interoperate / select the most
 appropriate components to further their goals.

 incredibly, without this simple interface at this absolutely
 critical critical juncture, that just... cannot happen.
