Sender

[smeagol]

Is it possible to make a script in which, when someone sends something to your wallet, you can automatically send them something back (maybe 1/2 chance of doubling money)?  (Kind of like SDICE)

Yes, very easy*

*Depending on your coding skills.

A lot easier if you use an online wallet like blockchain.info.

2 Ways:

Poor mans way:
Watch the wallet address in a loop, ever n seconds / minutes.  Query transactions.  Double the send.  You might need to worry about double sending in this case though.  Might need to persist the sent transactions, and verify that you haven't already sent.

Or:
Configure blockchain.info with a IPN.  When received, double and send.  This would require a service / site hosted somewhere, locked down, extra security etc.

I could knock up a console app to do it, with config, for 2btc

Double the send half the time, is it possible?
And what is a console app?

Sorry, what do you mean by "double the send half the time"?

Anything is possible, if you diffine your bussines logic.  By console app, I mean an exe that just runs in command prompt without a GUI.  This is one I wrote to poll Mt Gox.
