We are this >< close to exhausting > the current 32-bit address space... Is there a seperate address family for this? I have some experimental stuff I never followed up on (it would require being able to use dlopen() in a statically linked binary, which you couldn't do at the time) to unify the address family management functions. My plan was to get the XNS and ISO and X.25 code back from Limbo with it. It seems to me that the same code could take care of your problem; if you could look something up without resorting to naming the family you are looking up, then all of these things would be transparent. As usual, I got busy digging the moat instead of building the castle ;-), and went of on a tanget trying to get a netbios address family wedged into the kernel so Id have something to test with (the XNS/X.25/ISO stuff needs to be brought up to date as a matter of principle, not because I actually have any hardware that can use it 8-)). Basically, it takes the resolver library and loads shared objects based on address family space in which you are looking. Novell did something very similar for the port of the Portable NetWare (later NetWare for UNIX) code to the NeXT machines.
