Nagios as Cron

What is the community's views on using Nagios as a sort of Cron daemon? 
I've got a process that runs hourly in cron that downloads an updated data 
file from another host. The process takes about 5 seconds. The timing is 
not critical as long as it eventually gets executed. I want to know if the 
process fails (ie can't connect to the remote host, can't get the 
datafile, etc).

I could have the process send a send_nsca message indicating it's status
and run it out of normal cron, or I could call it as a plugin. Calling it 
as a plugin seems aesthetically wrong to me as it has definite 
externalities, as opposed to merely monitoring something else.  Does 
anyone else use Nagios in this manner? 

Another issue is for maintence jobs that run once per day.  An example
would be a app-specific log rotation script.  I need to know when these
fail as well.  In this case it pretty much has to be run from cron and use
send_nsca as the timing is important.  Can anyone give me some ideas on 
how to handle these sort of jobs?

Thanks,
