Florian,

I've got some software to talk to a Wiener crate over ethernet via SNMP.  It's based on some ASYN device support that John Priller created.  This has been running for the STAR experiment at BNL for about a year+.

We're controlling three of the ISEG EHS 8060n modules in an MPOD crate.

Let me know if you'd like to take a look at the code.
