Yes, I see no technical problem for having such option here but
regardless the possibility on having that tool (not available yet) you
still can make use of the snapshot repository to get an older deb
package, for instance, when an upadate renders the new one unusable or
simply is broken.
Anyway, using the stable version of Debian (now Squeeze) should prevent
for that things to happen because only security patches are going
through the update routine and that's precissely one of the reasons for
recommending stable releases for production systems and servers: things
break less :-)

Yes, I also have a bunch of windows systems to administer so I also
have faced malware situations but in my case, restore points were of no
use becasue of the nature of the malware (viruses are eaiser to remove
but rootkits are a real pain and you can't get rid of them by restoring
the system to a previous state...).

That's similar to what virtual machines provide by menas of the
snapshots, which I also find really useful.
