I am currently at the TechEd conference and it has been a very rewarding experience so far. It's amazing to hear what everyone is using our product for - many of them ideas I had never thought of. It's also interesting learning about the other pieces of Office Communications Server. From the Application Server perspective I do not get very much insight into what Live Meeting and Communicator are capable of but I am quickly ramping up.
Several of you may have attended my talk on Tuesday about the UCMA API. For those who weren't able to make it, I discussed using UCMA to create an alerts application and a simple bot. When I return to Redmond I will post the code for this sample and I will start up a new series on building bots in UCMA as I have run across several tricky points.
