The major technical challenge is that sensors are not documented on the majority of systems, unless you know in advance where to look for them. IPMI and ACPI tries to do something here, but the former is only available on serverhardware and the latter more often than not, comes only with the minimum necessary to avoid melted plastic. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
