I've just switched to fcron, it's not a straight drop in AFAICT but not 
exactly hard.
   * crond needs changing to fcron in rc.conf DAEMONS
   * You'd need to backup/copy over your crontab from dcron over to 
fcron as it
      either overwrites the old on or uses one from a different location.
       (dcron syntax is working fine in fcron though)
   * crontab cmd is a little different (as the install msg tells you)

If (big if i know) the default cron is going to be swapped out, the only 
thing i would suggest is warning in advance so people can backup crontab.

+1 from me though for swapping, fcron looks a lot better/more versatile 
to me a humble user!
