I don't get too much into the IT automation work flow software -- it's a crowded market and just something I haven't been able to play with much. Since reading about the Citrix Workflow Studio, it seems to be a pretty cool product. Gus Pinto covers the product on his MVP blog and thinks it is revolutionary.
This may be a stretch -- but I wonder if Citrix could/would buy Platespin?
Also.....Citrix is keeping it's promise on its Xen acquisition as well --- a new commercial version of the Xen Server is set to roll out and Citrix Presentation Server has been renamed to XenApp.
