Hi,
Take a look at the 'views and filters toolkit' on codeplex
http://crm2011ldgmanager.codeplex.com/
This is a set of custom workflows and the 'instantiateFilter' can enable you to deploy more complex offline filters that you can't do via the user interface. I used this for a customer who wanted to take contacts offline who they were connected to in
addition to the records they owned.
