There are lot of things related to Interoperability.
Here i am giving compiled links with some introduction about those links that i have .
I think it covers all about Interop in .NET realted to Software Development scenario only.

Interop in .Net

1. COM -> .NET and .NET ->COM
http://www.codeproject.com/dotnet/COM_DOTNET_INTEROP.asp
This article provides a technical overview of .NET and COM interoperability with good diagrams. This shows what happens and how you need to manage interop inside and in-depth in this scenario.

3. CLR and JVM (Interop between .NET and JAVA)
Two possible ways,
3.1 Web services
This is the hottest topic now a day in IT industry because of its flexibility and its power.
There are lot of tutorials on net that how to develop web services in .net but our purpose is the interop issue so i am giving here some sites that helps in interop with web services.
www.ws-i.org
Most important site that gives all about interop for web services as this is dedicated organization for interop issues in web services.
It provides a Basic Profile (standard/specifications) that covers more than 150 interop issues addressed in web service development related to interoperability.

This is Microsoft link that provides a very good article regarding Building Interoperable Web Services in .net - gives everything enough.

3.2 Third-party tools
I didn’t use it so don’t know much but have few links,
http://www.borland.com/janeva/
Borland's Janeva that can be use for CLR and JVM interop
