I gave it a try and it did just fine for multiple devices. Problem is that there is at least one NAS I would like to connect which has only support for nut. Since all devices support nut, I hoped I could give nut a go. If it's not possible to install both packages at the same time, I would need to leave the NAS without any shutdown or buy the expensive network management card from APC (that seems to be supported by nut without apcupsd). Thanks for your answer though. I'm just hoping for another way.
