PropMod all the basics of a propeller based system + code security

I have developed and built a 40 pin 0.7" pitch dip module that contains:
*Propeller
*5Mhz Crystal
*512kbit EEPROM
*PropPlug Header
*Fusible Code Security System
*3.9V short term over voltage protection
Optionally:
*uSD Card Reader
*Real Time Clock
As you can see from the picture there is no physical access to the eeprom or propeller. There are no markings of any kind to let potential attackers know who made it or what it does(Though please tell your friends about it.)
The pin layout is not the same as the propeller this also helps mask what it does. But I do have an adapter board available to allow for use in existing prop dip package boards. The uSD card is inserted on the bottom side of the module on the boards edge. This can be difficult to get at so if you want people to see where it is and have access often I can mount the headers upside down.

I have not yet setup paypal automated payment system but you can order by emailing me at squarerootofnegativeone@gmail.com or sending paypal payment to that address.
Prices in Canadian Dollars(See www.propmodule.com/?x=products_propmod for exchange rate):
1-9: $60
10-24: $55
25+: $50
uSD option; $5
RTC battery not included $10
World Wide Shipping is $15
Last but not least for a limited time only I will give bulk discount based on all orders not personal order. Meaning if 10 people order 3 each everyone gets the +25 rate.
Orders for this bulk discount must be in by April 21. I have 6 in stock and those can ship immediately any orders beyond that I will ship within 2 weeks of April 21.
If 50+ are ordered I will permanently lower all the prices.
Any questions?
