Why not simply > pass it to a daemon ? What I like about the OpenBSD framework is, that you can get the sensor=20 data with basic tools. What's wrong with "everything is a file"? With a=20 file system you don't have to jump through any hoops to provide=20 concurrent access to more than one reader. You could easily create=20 symlinks to map sensors to location. You have means to restrict access=20 to certain sensors. etc. ... I'm not sure that you can write the one daemon that suites all needs, but=20 if you provide all the sensors in a central place accessible through=20 basic tools it's easy to write a shell script that does exactly what you=20 need. =2D-=20 /"\ Best regards, | mlaier@freebsd.org \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | mlaier@EFnet / \ ASCII Ribbon Campaign | Against HTML Mail and News --nextPart1356896.QVs3KXlYjZ Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4 (FreeBSD) iD8DBQBHFnQHXyyEoT62BG0RAv95AJ9/fOumHwX315YdyO7YGIP47jsykgCfRt4p 8vAP+9ePG9A3AvXH5IXwa3U= =pFOY -----END PGP SIGNATURE----- --nextPart1356896.QVs3KXlYjZ--
