I do remote YUM updates on my servers frequently.  I've only had a few 
problems over time, most of which have little or nothing to do with the 
update itself.  IE, a hardware problem being discovered due to a reboot, 
or the reboot taking far longer than expected due to the machine having 
been up for around a year and an FSCK was forced.

Overall, CentOS w/YUM seems pretty rock solid.
