I use a little SQL table.. there are MySQL modules for almost any popular (and
not so popular) OS and language.. except DOS but I don't give a fig about DOS
anymore :)

Uh, what did I just say? If the rand() is prefixed with year, month, day,
hour, minute, second, millisecon, the rand() would have to return the same
number twice in that one millisecond.
The only issue here is if rand() is seeded by the time, in which case multiple
processes will generate the same sequence of 'random' numbers (again, this will
have to happen during the same millisecond in both processes). But on any
non-shitty OS (ie. not DOS) there will be a system wide source of randomness or
other information that will keep two processes from picking the same number.

Which means using a single source.

Good idea, but rofl!

Was it decided that three fields in MSGID would break things? If software is
currently only generating one field then I can't see it being any worse.
