A dev command line prompt that simply ran through all the models, generated the IBXs and then exited (Like the export SEXPs and Export scripting command lines) might be nice though. No idea how simple it would be to do though. If it's trivial it might be worth someone more familiar with the model code making it. But it's not worth someone spending more than a few minutes to make really.
It already exists, though it may not be obvious. Using the -pofspew cmdline option will load all POFs, dump info on them, and then exit. As a process of this, all models which don't already have an IBX available will have one generated.
So it's quite easy to generate IBX files, and you don't even need to have that POF listed in a tbl or anything. It simply looks for all .pof files than it can find and tries to load them. All you have to do is (if you wanted to do this on a regular basis) create a "ibxgen" mod, which you would have data/models, and data/cache under. Put POFs in the appropriate place, then run the game with -pofspew and -mod ibxgen. It will generate all of your IBX files for you and dump them in ibxgen/data/cache. Assuming that you would always keep IBX files for all other POFs available, then ibxgen/data/cache should only have IBX files for the models which you had in ibxgen/data/models. Then you just have to pack them in a VP.
That's what I do anyway.
