Randal I can think of two ways to do this right off. 1) A file that is defined as a directory to both Universe and Unidata. Of course one or the other server would have to be mounted on the other's filesystem in order to "see" this alien directory. (Please forgive me if my nomenclauture is incorrect). If you are concerned about a single directory having hundreds of thousands of files in it, cannot they be defined as dynamic (Unidata) or distributed (Universe) directory structures? I.E. one directory with hundreds of subdirectories (or as many as you wish) each of which have hundreds or thousands of files in them. To Unidata and/or Universe, it should see this huge structure as one "file". Right? 2) Have the file be native to one system and setup a phantom on that system that wakes every five seconds, minute, or whatever and looks for something to "do". The other system then, writes out updates to a "waiting" area and trips a flag for the first system to "do" something. When the phantom wakes up, it sees the flag, grabs the update and updates the file. The second method works just fine if the file in question is some sort of log type file. Not as well if its not, but its still possible to fudgilate the systems to work. I remember setting up a interactive, multi-user, multi-computer type update like this years ago to allow an ADDS to update files on an Ulimate using Mentor/Link and set of fancy schmancy (technical term) set of routines to co-ordinate the lock tables. Most multi-computer schemes require operating systems from the same vendor, but with six months and a lot of free time and code that negotiates the first four or so layers for you, you can do it yourself...
