Believe it or not, this is very similar to how we handled the guest list for our fraternity parties in the early/mid 2000s at CMU. Everyone who wanted to explicitly invite certain guests (we actually had to keep a fairly strict door for a variety of reasons, not least of which was that a good frat party at CMU could have 300-400 people there concurrently) would have to create a text file in their public folder on Andrew, chmod that file to be read, and place with line separators up to 10 Andrew userIDs to be read and compiled by a script. It worked fantastically, aided no doubt by the fact that our house was ~50% ECE, CS, or IS majors.
