Sorry about the low stars. Looked at it quickly and as far as I can tell there is nothing wrong with this program, except that WakeOnLan is so very very much easier to use that I can't see switching to this one.
I might consider using WakeOnMac if at the very least it added the ability to automatically discover wakeable Macs and PCs on the LAN, instead of laboriously entering network data for each.
Looking forward to both apps improving through competition.
