[P2P-F] Contributing to p2p

[sindikat]

Hi all! 

I'm a strong supporter of free software and p2p technologies, however not 
too good in technical aspect. I have around 200$ and want to buy a VPS to 
setup several things i always wanted, but before doing it i want your 
advice. 

First of all i want to setup my own IMAP/SMTP server to have all my mail in 
one place (mail from other addresses will be forwarded to it). Then maybe 
ownCloud to store and synchronize movable data. A jabber-server maybe, 
because many jabber servers unfortunately are not so reliable. And also 
something that will contribute to P2P movement. 

But what would you suggest? What software should i install and configure on 
my VPS? Is it possible to configure it as Tor node or other stuff like 
that? Maybe i shouldn't buy VPS but something else? Should i encrypt it? 

Of course if i had more money myself or would be confident about donations 
from others, i would setup something public like Diaspora pod or file-store 
or whatever. 

And of course ideal situation is something like buying plug computer with 
FreedomBox, but right now it is not really possible. 

Looking forward for your advice.
