[p2p-hackers] Re: Identify "defective" nodes

[Sam Berlin]

I've been meaning for a very long time to add a plugin architecture to
LimeWire, for things such as Credence and the like.  If anyone here is
interested in such an addition, so they can provide their own add-ons
to the program (and be able to ship just the plugin, not the whole
program), please let me know.  I'll attempt to gather up what folks
are looking for in an architecture and write something suitable.

Thanks.

Sam
