Awesome; what I've learned so far is that I'm missing out by not using one or the other. I know screen a little, so I guess I'll start there.. stupid, too - its exactly what I've needed on many occasions. Derp.

 Ga> Here's an example of one way that I use it.  I have an Raspberry Pi 
 Ga> running 24x7, which does various things for me (it does not run my BBS 
 Ga> though).  I SSH to it from my laptop (either from within the LAN, or 
 Ga> remotely from another state if I'm traveling).  I have opened a screen 
 Ga> session on it, and started the 'irssi' IRC client in that terminal.  
 Ga> This connects and idles in the Synchronet IRC channel.  I then can 
 Ga> detach from that session (with Ctrl-A, D), and close my SSH connection.  
 Ga> A few hours, or a few days later, I can SSH back to the RPi, restore my 
 Ga> screen session (with "screen -r"), and BAM! my irssi client is there 
 Ga> where I can scroll back and see what's been talked about while I was 
 Ga> gone.  Maybe I add some comments, whatever.  Then I detach and close 
 Ga> again, and the irssi client continues running while I'm gone.  This 
 Ga> allows me to maintain a "presence" in that channel even if I'm not 
 Ga> actively watching it for a while, and I can catch up when it's 
 Ga> convenient for me.  You can open as many screen sessions on a remote 
 Ga> host as you'd like, all doing something different, and all will keep on 
 Ga> working after you detach.  Pretty cool stuff.

Yep... awesome. :P I'll be doing the same exact thing shortly. Like I can have one Raspberry Pi that allows me access to my local network and screen around from there. Again, I'll brush up myself but... seems like I can have a few things 'screened' and ... I'm sure theres a way to get a list of whats open on what screens... :P 

I should have investigated this long ago - as I've used it with irssi, too, to put the handle lists on the right hand side of the screen - but I didn't realize that it does much more for the type of computery stuff I do all the time. :P 

(I'll admit that I've used VNC to do much the same... with a lot more resources that screen would take. Ugh.)
