1) Is it possible to choose approvers depending on user answers in resources?
For examle user made request for new computer. He choosed laptop from drop-down list in resources(pc, laptop).
Can system automatically send e-mail to laptop-approver

2)  Is it possible to choose approvers depending on requester relationships? May be there is any scripts that can help?

I know only about $Dept_Head$ feature
3) Is it possible for users to choose more than one stage of approve?
For example user choose 2 approvers in web-form. But only 1 of them must approve request.

Thanks and sorry for my bad English.
