BFL products including the Jalapeno is ASIC hardware, which only works for BTC.
Altcoins use Scrypt, which need to be mined using GPU or regular computer power.
Wrong, wrong, wrong.
Not all Altcoins are script based. A few examples include Namecoin (NMC), Devcoin (DVC), Ixocoin (IXC)...
Any SHA256 altcoin can be mined.
All others, can't.
BTW, this is an quite answered question, in this forum.
