There are already options to publish hardware information to a bunch of different places, however there are two other places that would still be useful.
First, the data should be pushed to the perfmon subsystem so that the Windows built-in tools can access the information directly. For example, the Win7 Performance Monitor application under the Management system could use this data to build graphs for for CPU clock speed and temperature. There are many tools that use perfmon data in this way. WMI gets you part of the way there but until the data is published as perfmon classes it will always be less useful.
Similarly it would be nice to see an AIDA64 SNMP extension DLL that added well-known OIDs for different counters. The existing Windows SNMP agent can be used for the main interface, so all you need is an extension agent. I can help you figure out issues such as OID namespace and MIB structure if you think it would be helpful.
In conjunction with the ability to run as a service, both of these would open AIDA64 to full-time deep monitoring of always-on systems
