Coming from Perl, I use a combination of the system time and the process
ID as the basis for a unique ID. I don't know if Ruby has anything
ready-made for this, but it would be nice if it did.

MD5 and other hashing algorithms are susceptible to collisions, so you
won't necessarily get a unique ID even if the original data is unique.
