Here is the first part of your good news.

I have put up the vector clocks module here:

http://code.google.com/p/vclock/

Vector clocks become much more useful once you also have Merkle trees.  I
will package up and release an implementation of those soon as well.

However, since vector clocks can be useful on their own and I was able to
get this part out more quickly, I thought I'd give you something incremental
to look at.  It is not a large amount of code, but we have found it quite
handy.

Best,

-Justin
