Please remove alpha, mips and m68k distributed-net packages

thanks

Hi,

I'm the maintainer for distributed-net.

Upstream provides binary builds for various architectures.  I cannot 
build for other architectures (combination of license and crippled source).

The latest version in unstable is 2.9008.490-2.  Upstream no longer 
support alpha, mips or m68k and the older binaries no longer work with 
the current infrastructure.

If this isn't the right place to beg for help, could you please point me 
in the right direction? :)

Cheers,
Stephen
