JXcore,
http://jxcore.com/home/ is an extended node.js fork which adds more features. It also reduces the size of an application to where complex code can be less than 100 Mb. Bringing this into Lisk can make it even more compact than the 512 Mb it takes now.

Lisk enables much more than just micropayments among IoT devices. Lisk dapps can secure an owner's cloud of IoT devices against hacking and man-in-the-middle attacks with DNSchain type technology,

We have been waiting for the 0.5.5 release to run it on Bitseed,
https://bitseed.org/ , an Bitcoin full node with 1 Gb RAM, dual core ARM processor, 8 Gb eMMC, and 1 Tb hard drive storage. We have also shipped some with SSD instead of the hard drive.
Yep keeping a close eye on JXcore and have already tested it with Lisk.
For the moment it's based on a older version of node (v0.10.40) with functionality backported from upstream, and certainly has some nice features of it's own.
The "quick load" feature that Crypti/Lisk has implemented makes the biggest difference imo, especially when running on these low-footprint devices. So for the moment we will stick with the original

I have a Raspberry Pi 2 chugging away as a Crypti delegate, which has been up since I launched it several months ago. Therefore operating a delegate on these devices, providing you have a good network connection is a definite possibility.
