After very long time (more than a year!) here is update to my Wake-On-LAN program.
This update consists mostly of bug-fixes with single new feature. One can define custom wait period between sending packets. This change will not be used much but for situations where you need to wake hundred of computers without burning fusebox it is definitely crucial.
Additional small tweak that may stop some frustration is change of console tool to wol.exe. This way one working in command-line can write only three letters instead of eight (it was magiwolc.exe).
