If anyone has a functioning silverlight/moonlight plugin and a paid (or

Quite right - it's essentially a tin-copper alloy.

BS EN ISO 9453:2006 Alloy 401:

Impurities, max. %:

Pb 0.1
Sb 0.1
Bi 0.1
Au 0.1
In 0.1
Ag 0.01
Al 0.001
As 0.03
Cd 0.002
Fe 0.02

Other

Cu 0.5-0.9%
Sn remainder

.... Has anyone written a Silverlight stream to PDF converter yet...?
