Article / Document about passwords vs. passphrases

Hi list(s) sorry for crossposting but I think this is "relevant" to  
both lists.

I wrote an article about secure(r) passwords and easily formed ones  
aimed at the "user" level which can be found here: http://blog. 
2blocksaway.com/2006/10/29/easy-passwords-that-are-secure/
I then proceeded to send this to some of my clients in pdf form and  
as weblinks and i got quite a few mails this morning regarding it,  
some of them good, some of them bad. And the bad ones i need some  
help with.

I was told that Windows vista will not let you use (SPACE) in your  
password , can someone confirm or deny this? also someone said that  
only the most recent version of linux allow you to have long  
passwords, according to my memory, this has worked already for a  
looong time (i remember i used a long password quite a few years back  
already) so any info on that would be good too. Any pointer as to how  
to improve this article would be excellent since quite a few of the  
people I know use my stuff as reference and I wouldnt like to be  
"that" wrong :)

Thanks already for any help, i appreciate it.

regards,
