sure.
I've attached an updated (and not yet published) version of the NUT
simulation info.
You will find everything you need to simulate as many UPS, PDU, (...) you want.
Since manpages links are broken, also use the online version:

NUT is included in small footprint appliances (10 Mb) such as Opengear
devices, so this should not be an issue.
A full (Ie including the world) distribution on Linux weights ~4 Mb
But you will be able to cut it down to 2Mb or even more... at least on Linux.
- 350 Kb for (5) USB drivers
- 94 Kb for snmp-ups
- 54 Kb for nut-ipmipsu
- 43 Kb simulation driver
- 200 Kb lib (nut client and scan)
- 14 kb nut-scanner binary
- 26 Kb for Nut.pm
- 51 Kb for upsd, but you can also directly talk to drivers and remove
upsd (ex: if you just want to launch drivers from time to time, to
update data...)
- ...

NUT depends on libc/equiv + libusb + libsnmp (Net SNMP) for your requirements.
For other options (SSL, IPMI, ...) requirements, check this chapter
and the following:

> Is it possible to use nut on Windows?

sure, NUT now runs on all OSs, including Windows (not yet as complete
/ mature as Unix versions), Linux*, OS X, BSD*, HP-UX, Aix, Solaris,
Qnx, ...

Windows and other packages are available:

cheers,
