Does Vanguard grant admiral shares only on a per-account basis?
Yes, each of Vanguard's mutual funds looks only at its own shares when deciding to upgrade/downgrade the shares to/from Admiral status. To the best of my knowledge, if you hold a fund in an IRA as well as a separate investment,  the shares are not totaled in deciding whether or not the shares are accorded Admiral shares status; each account is considered separately.  Also, for many funds, the minimum investment value is not $10K but is much larger (used to be $100K a long time ago, but recently the rules have been relaxed somewhat).
