If you're interested in transactional programming, you're in for a treat. 

Paul Fallon, who's handled more transactions than most major banks, is giving a presentation called Transactions in .NET - Today and in the Future at next Monday's NIMTUG meeting in Belfast, and again at the March 24th developers.ie meeting in Dublin.

If you're interested in how the System.Transactions namespace in .NET 2.0 unifies and simplifies transactional programming, this is one not to be missed.
