This article on how to set up an out-of-state deposition is the best I've seen on the subject, even though it is dated.
The Maryland Court of Appeals has issued an opinion that holds that a named driver exclusion endorsement is not prohibited by Maryland law in a commercial automobile liability policy. This opinion is discussed in the relatively new Maryland Injury Law Blog. I am sure I will be a regular reader of Miller & Zois' blog.
I previously wrote here about the intermediate appellate court's opinion in this matter. Because it found that the named driver exclusion endorsement is valid in the context of a commercial auto policy, the Court of Appeals did not address the second issue that it had before it, namely, "whether a declaratory judgment that there is no coverage for a particular claim, entered in an action between the insurance company and its insured, binds a person who (1) has filed a claim against the insured, but (2) was not a party to that action."
