Not sure if you're looking for a bouncer to stay connected all the time or because you're afraid of your connection location being revealed.
If it's the latter, you can always request a vHost on a per-network basis.
Most networks support it (and some trackers, by default, set you one with your user class in it)
Once yours is requested and approved, it sets itself every time you auth yourself with nickserv
Generally, the command to request one is:
/msg hostserv request whatever.vhost.you.want.here
