Thanks!

However, I think the best idea is to use generic Exceptions, if I try to
use the CookComputing.XmlRpc Exceptions I need to compile ALL my
application with CookComputing.dll and I'm not looking that, that's why
I'm working with plugins to just compile CookComputing.XmlRpc in the
plugins and not in all the application.

Thanks for these suggestions!
Pablo
