cyber beneficiaries

     What happens in cyberspace when you die?  I have read more than one article on this subject recently. A practical way to deal with the problem would be to have the option of designating a "cyber beneficiary"--someone with the legal right and capacity to deal with online accounts for someone who has died. The executor or executrix of an estate, or someone with a durable power of attorney, ought to be able to access online accounts. But how are they to get the passwords, or to know where the accounts are? Anyone who dies with money in an online account has probably left it to someone in a will--but collecting it can be difficult, if not impossible. Another instance where we don't need any new laws--just a "concession" that the laws of physical space also apply to cyberspace.
