<DIV><FONT face="Arial" size="2">I'm hoping
to use the 16F877 for my initial development, then move up to the 18F452,
it should have enough memory to handle IP, xPL and still have more
than enough space left over to actually do useful
stuff!</FONT></DIV>

<DIV><FONT face="Arial" size="2">POE is a
definite requirement, but Cisco's probably isn't... it's the opposite
polarity to everyone else!</FONT></DIV>

<DIV><FONT face="Arial" size="2">That being
said.. I have this idea that if I use a bridge rectifier on the power
inputs, it will automatically give me both polarity protection for DC
power, and also rectify AC power, so *in theory* with some clever component
selection (max reverse voltage etc) </FONT><FONT

48V DC, Intel -+ 24V DC, or Homebrew -+12V AC</FONT></DIV>
