Excuse my lack of knowledge, but seeing as how one BTC is now worth $100. Is it possible to send someone half a bitcoin or 1/10th?
Or is it a single unit or nothing?

BTC can be sent in any amount, all the way down to Satoshis at 0.00000001 BTC.
Also there is talk of making the default traded unit a mBTC, (I think) Its a unit that represents a thousandth of a unit. once this becomes the standard unit the psychology is there to allow BTC to rise even further.
