Re: [Jgroup-users] Group discovery

[Brian F. <bfo...@ya...>]

Hein,

Thanks for the response. I'd like to use it in a LAN environment where
the software will be deployed at customer sites while avoiding
generating site-specific config files at install time or when a system
is reconfigured. But it sounds like that isn't a good use for Jgroup.
