+o split rlm_files into rlm_users, rlm_fastusers (in-memory hash),
+ rlm_detail, rlm_dbm... they all should share as much code as
+ possible though, not be big cut-and-paste jobs
+o New module: rlm_attrmap. assigns a single attribute based on a
+ username, with ed-friendly/awk-friendly config file. Because the
+ users file is too complicated.
+o New module: rlm_fastradwtmp. with a radutmp-style active session
+ database to guarantee wtmp records are always written in matching
+ pairs. Because radlast is slow.
+o New module: rlm_nsupdate (dyndns). Because dynamic addresses are
+ cruel.
+o New module: rlm_perl.
