Base58Check encoding: Using for Version 4 UUID? Can Base58Check encoding be used to encode a Version 4 UUID?

This would be handy for the same reasons as encoding Bitcoin public keys in Base58Check instead of Base64.

I've read the Bitcoin wiki pages on address encoding and the list of address prefixes, but it isn't clear whether Base58Check encoding can be used reliably for version 4 UUIDs without reserving a prefix somehow. For example, U for UUID.
Nothing is preventing any sort of data from using Base58Check encoding, but I'm not sure why you would want to. There's already a multitude of 'altcoins' using a variety of address prefixes though, so you might run into issues should one of them become a real-world success. 

In reality, I'd just avoid having users typing a UUID-type string at all, then you don't need to worry about having the typing friendly characters and checksum.
