Michael,

 Since libcoin is "chain agnostic", I was wondering if the project can be
used like this:

 When I install it with "make install", I would like to have something like
this:

 Regular file: /usr/local/bin/libcoincore # or whatever you like

 Symlink -> Regular file

 /usr/local/bit/bitcoind ->  /usr/local/bin/libcoincore  # bitcoind is a
symlink to libcoincore

 /usr/local/bit/litecoind ->  /usr/local/bin/libcoincore  # litecoind is a
symlink to libcoincore

 /usr/local/bit/devcoind ->  /usr/local/bin/libcoincore  # devcoind is a
symlink to libcoincore

 /usr/local/bit/namecoind ->  /usr/local/bin/libcoincore  # devcoind is a
symlink to libcoincore

 ...and so on...

 So, libcoincore will interpret the ARGV[0] and, for each string, it will
initiate the appropriate internal functions...

 I don't know if Libcoin already does something like that... I'm not a
developer/code reader... Just a small nerd with big ideas...  ^_^

Thanks!
Thiago
