Hi,

As part of the support for FI encoding algorithms i need to produce or
consume UUIDs.

I started writing a UUID class, got 10% of the way and realised this is
going to take a little bit more work so did a little search and found
that JDK 5.0 has a class which looks suitable.

I now have a couple of choices:

1) Do not bother with the UUID class and keep the interface very simple
e.g. msb and lsb of the UUID as two longs, then people who use 5.0 can
easily create a UUID class from these longs or produce longs from the
UUID class.

2) Port the 5.0 UUID class to 1.4.2. This may involve licensing issues too.

So i think the best thing to do is go for the first solution that does
not presuppose a the use of a UUID class.

Paul.
