I always thought being able to tag nodes would be useful (ex: web, web-lighttpd, web-apache, database, storage, dmz, etc...).

To be clear, I don't want something as complicated as an ORM or Casey's example, per se, I was pondering whether the "run this if" example is interesting.Michael DeHaan wrote:

What if we had an ORM for systems? When he first posted it, my initial thought was "Func already does this", though there are some subtle changes:
His example was more complicated, but what if we could do something like:
Client("*.example.org").filter_by(arch==i386).services.start("httpd") ?
(I'll admit the critera syntax could be much better)
The only new thing here is the concept of filtering. The goal here would be that instead of getting back the inventory for each system, we instead find a way to send the conditional "run this if" critera down to each node. This may be better served as a library a level up from Func, so we could also work on having more "objecty" returns for it if we wanted to do this -- ultimately this might mean it's our higher level Func API after all.
It does seem to want or require something like a facter, but I need to evaluate whether that would meet the needs for what I want to do -- I suspect it's not sufficiently Pythonic and we may want to do something different.
Anyway, doing something higher level and primarily using Func for (secure, audited) transport may not be such a bad idea.
Here was the post: http://www.michaeldehaan.net/?p=821
Either way, I think the above could be done by outsourcing the decision making to the nodes, so we don't have to keep an updated database of all the nodes properties.
