* ldap for auth (and maybe actors?)
* cdb (for static content, maybe? does this make sense?)
* mariadb/mysql
* the various nosql horrors, e.g. redis, mongo, and so on

parsav urgently needs an internationalization framework as well. right now everything is just hardcoded in english. yuck.

parsav could be significantly improved by adjusting its memory management strategy. instead of allocating everything with lib.mem.heapa (which currently maps to malloc on all platforms), we should allocate a static buffer for the server overlord object which can simply be cleared and re-used for each http request, and enlarged with `realloc` when necessary. the entire region could be `mlock`ed for better performance, and it would no longer be necessary to track and free memory, as the entire buffer would simply be discarded after use (similar to PHP's original memory management strategy). this would remove possibly the largest source of latency in the codebase, as `parsav` is regrettably quite heavy on malloc, performing numerous allocations for each page rendered.
