Low Voltage Stamps?

Greetings!
Anyone know if there's any plans for a low voltage BS chip?
2.5V to 3V would be grand...
(I'm working on a VERY small project, and batteries are taking up a lot of
space)
A step up DC-DC chip isn't the answer either because that means I have to
use batteries that can deliver double the Amperage. (I'm trying to make do
with 'button' size cells together with a BS1 )
Just wondering...
:-)

the time being, that would not be a fruitful project for us. Despite
appearances, we're very small and have limited resources. Right now our
target is cross-platform compiler so that customers can program BASIC Stamps
with nearly any OS they choose.

The BS1 is based on a PIC16C56, which does not have a brownout
detector built in. That chip is supposed to operate down to 3.0
volts at 4mhz. I see no reason you could not make yourself an OEM
BS1 to run at 3.0 volts. It would really get to micro power at that
level. That was always a great feature of the BS1--low power
operation.
I have made BS2 circuits that run on a stack of two coin cells in one
holder (6 volts). The circuit had a pushbutton to activate, then at
the end of the action, the BS2 turned off its own power supply for
zero-power standby.
