Got a RPi for Christmas :) and I'd love to set it up with online armory, so I can run a node as well as my wallet.  (Fwiw I have armory offline on an old pc).

Is this possible?  It's a B+ with 512Mb RAM. 

Many thanks

Barely. Bitcoin Core 0.10 will probably handle the low resources of the rPi better than previous versions (the 0.10 release candidate uses less memory and cpu in my experience toying with it), but for that you still need:

• Armory that is compatitble with headers-first block storage (version 0.93 apparently)
• Armory that can build it's DB from a device running bitcoin core at a network location that's different to where Armory's running (not sure when that's scheuled, but Armory devs have expressed interest in the past)
• An Arm build of Bitcoin Core (there's no official builds for Bitcoin Core atm)

0.9.x will run on the Pi, but it can become really unresponsive, really easily. And it's pretty much unusable becasue of it, although you can "improve" matters a little by increasing the size of the swapfile on the Pi (which, of course, removes more precious space from your SD card that is already a bit strectched for space, what with all that blockchain on it...)

Edit: maybe I misread your question, but if you want Armory and Bitcoin Core online on the Pi, then that probably won't happen before the Pi is near enough obsolete. 

Armory 0.93 requires a 64 bit OS in online mode. I can't imagine a workaround existing. the RPi is 32-bit.

Well, that seals it. As long as the transaction signing format doesn't change any time soon (doubtful, it changed for the first in a long time for 0.92), then the rPi will be a good replacement for that old PC if it's hard disk gives up on life. Sounds like the end of (online) WIndows XP Armory too, 64-bit XP was pretty uncommon really.

Yes, that is the case for Windows XP, online support. It was a consideration, but if you're using Windows XP, the machine is either pretty old and will be really slow for use with an online wallet, or you could just install a more recent windows if you want to use it online, which is a good idea since you'll then want security fixes from Microsoft.
