Regarding the decimal vs satoshi notation I see a few problems with satoshi:
* readability - humans reading the URI would expect it to accurately
reflect what is being displayed (subject to internationalisation issues)
For example, amount=1.234 is more human readable than amount=123400000 (ish)
* backwards compatibility - existing software already uses the decimal
notation
* forwards compatibility - Bitcoin needs to move beyond the satoshi to 20
dps for some reason, this remains OK within the existing schema, but forces
decimals into the satoshi scheme
* simplicity - dual decimal/satoshi variants should be discouraged under
the "single representation" approach
It's relatively straightforward to convert a string encoded decimal into an
internal integer for currency calculations just by applying a multiplying
factor. One never uses doubles or floats for money.
