Dreamcat4 and Lindsay,

thanks for the hints on integrating Capistrano. It's not what I had in 
mind, but I'll investigate the custom resource and the moonshine 
alternative to see how they fit in.

Msf,

From what I read from your mail, this is what I was thinking: making 
run_command, open4, system and so one ssh/remote aware. The caveat is 
that a lot of logic in scripts is handled by ruby internal code that you 
can't simply make ssh aware unless you implement it as a command line 
(f.i. copy files over ssh (handled in ruby code) instead of 'scp ...' 
command). Therefore I was thinking of flagging recipes with the remote 
execute capability flag : meaning it handles everything by commandline 
commands.

Anyone else interested?
