What Is Your Corporate Standard

If you are not a consultant and you work for a company then does your company have a corporate standard for development languages/products?
Our IT department is about 800 people and to get good support you can not have 3 thousands different products in your shop. As of today this is what is supported in our company

Java Stack
Sun's Project Tango
Apache Web Server 2.x
Tomcat 5.x (web container), JBoss 4.x (EJB and Web Container), WebSphere Network Edition 6.1.x (web and EJB container)
Hibernate 2.x, Spring 1.2.x
Sun's J2SE 5 (aka J2SE 1.5.x)
MySQl 5.x, Oracle 10g, SQL Server 2005

.NET Stack
WCF
IIS 6
.NET 2.0
CLR Version 2
MySQl 5.x, Oracle 10g, SQL Server 2005

Of course we have other things that we use ColdFusion, SQL Server 2000, that is fine but no NEW development is supposed to be done with those tools/products

So here is my question to you; what is your corporate standard?
