As suggested by NoahKirchner, Cargo should have an encryption key printer that prints out squad encryption keys only.
Benefits (How this will benefit the server and game as a whole): Late-join marines will no longer be without squad comms. Also if the CMO is having a lot of issues that require MPs, for example, you could print off an encryption key and give it to them so they can easily call for help without alerting the ne'er do well.
Details (Description of how you think this would work, the benefits, etc): It would be an autolathe-esque machine that doesn't require metal or glass, which you are required to insert your ID and log in to. From there you could print any Sulaco encryption key you wish.
Implementation (Optional, if you have an idea how to implement it):
