yea, i expected as much, which if fine, i just dont know how to go about 
doing so...  maybe there is a way to send a "wake-up" packet to the ram, 
or nvram, and have it execute it from there at a given time?   dont know 
too much about what can and cant be performed like that so, if im way 
off base, please forgive me.

yea it has helped, thank you. i have found a linux wake up procedure 
that i might be able to tether to my needs, if it works

<CODE>
 #!/usr/bin/ruby
 require 'time'
 wake_time = Time.parse(ARGV[0])
 wake_time += 24 * 60 * 60 if wake_time < Time.now
 File.open('/proc/acpi/alarm', 'w') {|f| f << wake_time.utc.strftime
    (%Y-%m-%d %H:%M:%S')}
 system('/etc/acpi/sleep.sh force')
</CODE>

like i said, this is for linux, obviously, which if it works takes out 
one of my issues, but what i dont know is if there is anything like the 
above file locations for windows or mac?

well, ill keep looking around, maybe i can dig up something else using 
this as a search tool, any additional help or advice is much 
appreciated.
