I've been developing web applications with Rails for about a year and a half
within the IT department of a large Oil and Gas company downtown.

We use JRuby and deploy to Tomcat. We've had a lot of success and productivity
over the likes of Java's Struts and Spring have been quite impressive. But even
as we transitioned to this environment it seems the rest of the company is
transitioning to .NET.

In general it seems like the entire IT community downtown is turning to
Microsoft. Is that true? or are there other pockets of Ruby and Rails that I'm
not aware of?
