I've noticed that the InfiniteWP solution for doing bulk updates of WordPress core / plugins / themes will fail if Better WP Security is installed, and all the checkboxes are enabled under the System Tweaks page, Dashboard Tweaks section. These checkboxes hide updates from users that do not have rights within WP to do updates. Disabling these checkboxes will enable InfiniteWP to do bulk remote updating.
This is a viable workaround, so not sure anything needs to be done, but it'd be great if you could look into it.
One other thing - I notice that these checkboxes are designed for use primarily in Multi-Site installations. When I have them disabled on single-site installs, they show up as a red 'unsecure' item in the Better WP Security dashboard. Perhaps you could mark it as 'yellow' for single-site installs, and red for multi-site installs, if they are unchecked?
For tracking both ends I've logged a forum incident with InfiniteWP @ http://infinitewp.com/forum/issues/better-wp-security-plugin-tweaks-stop-infinitewp-from-being-able-to-update/
